Noah Cameron has been one of the best rookie pitchers in the American League this season. When the 26-year-old Kansas City Royals southpaw takes the mound tonight against the Chicago White Sox, he’ll do so with a 2.52 ERA and a 3.67 FIP over 16 starts comprising 93 innings. Moreover, his 6-5 won-loss record isn’t representative of his overall effectiveness. In his five no-decisions, Cameron has tossed 29 innings and surrendered just one run.

Ranked third on our Royals Top Prospects list when it went up in late May as a 50 FV prospect, Cameron was described by Eric Longenhagen and James Fegan as “a very stable rotation piece… though he lacks star-level stuff.” That assessment rings true. Not only does Cameron’s 92.2 mph fastball rank in just the 19th percentile in terms of velocity, none of his pitches stand out in a vacuum. By and large, the 6-foot-3, 220-pound lefty dominates lineups by mixing and matching with aplomb. This season, he has thrown 27.2% four-seamers, 19.5% cutters, 18.96% changeups, 18.0% curveballs, and 16.6% sliders. Any pitch at any time is his modus operandi.

“I’m more of an old-school pitcher,” Cameron told me recently. “I’m not a flamethrower — I don’t throw upper 90s or anything like that — so I more lean on reading swings, looking at scouting reports, finding the hitters’ weaknesses. My mentality is to keep guys off balance and try to get quick outs by attacking the zone early. I’m OK with a strikeout, but I’m also OK with a fly out or a ground out. Getting guys outs as efficiently as I can is what I’m trying to do.” Read the rest of this entry »

There’s no such thing as a perfect pitcher. There are guys with an incredible ability to spin the ball, but nothing to throw for whiffs at the top of the zone. (Mitch Keller and Matt Brash come to mind.) Some pitchers pump backspin four-seamers, but never settle on a reliable secondary. (Ryne Nelson, I’m looking at you.) Excelling at one thing often means being deficient at another.

Still, even if there are no perfect pitchers, there are some who come closer than others. Prime Gerrit Cole featured a carry heater and a firm slider with meaningful horizontal break. Jacob deGrom? Same deal. Some guys break our general understanding of the tradeoffs between certain pitch types. Most of those guys are aces. One of them is Ryan Bergert — at least potentially.

If that name rings a bell, it’s likely because Bergert featured in a deadline deal that brought him to Kansas City (along with Stephen Kolek, a rock-solid fifth starter type) in exchange for backup catcher Freddy Fermin. In these early days following the trade, Fermin is acquitting himself well, lining a bunch of base hits and striking out just once so far.

Fermin is valuable — especially to the catcher-deprived Padres — though not particularly exciting. He’s under team control for the rest of the decade, but he’s firmly locked into the “light-hitting backstop with excellent defensive skills” archetype. Bergert, on the other hand, strikes me as a guy with serious upside. Read the rest of this entry »

Jack Dreyer has been one of the top performers on a Los Angeles Dodgers pitching staff that includes no shortage of better-known hurlers. Amid relative obscurity, the 26-year-old rookie left-hander has logged a a 2.98 ERA and a 2.95 FIP over 46 appearances comprising 57-and-a-third innings. Moreover, only Yoshinobu Yamamoto has been worth more WAR (3.5) than has the 2021 non-drafted free agent out of the University of Iowa (1.3).

Our lead prospect analyst was early to the bandwagon. When our 2025 Dodgers Top Prospects list was published in late April, Eric Longenhagen described Dreyer as “incredibly deceptive,” adding that his whippy arm action delivers a fastball that has “20 inches of due north vertical break as it explodes toward the plate.”

The southpaw’s signature pitch wasn’t seen as plus during his injury-marred Iowa Hawkeyes days.

“In college, I was always told that I have average spin rate, so I can’t really throw my fastball at the top of the zone,” recalled Dreyer, who missed much of the 2019 season with a shoulder injury, then all of 2021 after undergoing Tommy John surgery. “I was told that I had a very average fastball. I kind of believed that, but then I got to the Dodgers and they were like, ‘No, actually, your stuff is really, really good. You can live at the top of the zone because of how your pitch moves.’ So, that’s kind of how I’ve adapted my pitching, using heaters at the top, which opens up my other pitches.”

Dreyer’s secondaries comprise a curveball that he’s thrown at a 10.8% clip this season, and a “bad slider” that he’s thrown far more frequently at 45.2%. More on the latter in a moment. Read the rest of this entry »

Prior to batting practice, pitchers stroll onto the outfield grass to play catch with each other. Keeping their arms loose is a primary objective of what’s known as “catch play,” but there is more to it than just that. As a rule, the pitchers are throwing with purpose, both in terms of velocity and making sure that their mechanics are in order. At times they are also tinkering with grips, trying to find — or rediscover — desired movement on a specific pitch. And then there is long toss. While not all pitchers employ the practice, it is common to see crow-hop throws from foul line to deep center field. One thing you’ll rarely see is the casual tossing of a baseball back and forth.

How do pitchers get paired up for catch play? Does it differ for starters and relievers? What knowledge can be gleaned from these partnerships? Are there teammates you would rather not have as a throwing partner, because they’re especially challenging to catch?

With those questions in mind, I talked to three starters (Garrett Crochet, Seth Lugo, and Michael Wacha), two relievers (Liam Hendriks and Kirby Yates) a position player turned reliever (Lucas Erceg), a pitcher turned pitching coach (Mark Prior), a pair of pitchers turned broadcasters (Jeff Montgomery and Steve Sparks, and a longtime bullpen catcher (Javier Bracamonte).

———

Garrett Crochet, Boston Red Sox left-hander:

“Greg Weissert is my catch partner right now. Honestly, it kind of happened out of necessity. It was Justin Slaten for awhile, but Slaten went down [with an injury]. I was playing catch with our bullpen catcher for awhile, but I prefer to throw with another pitcher. Typically, starters either play catch with each other or with a bullpen catcher. In Chicago [with the White Sox], it was mostly a bullpen catcher for me.

“When I was coming out of the bullpen in 2021, I was throwing with Michael Kopech and everything was just real hard and real scary. Sometimes with Weisert it gets that way, too, especially with the curveball he throws. It’s different for Greg and myself, too, because he has to be ready to pitch every day, whereas I don’t. I’m probably the one that he hates to catch. But no, he loves it. He’ll get down on one knee, use a catcher’s mitt, catch flat-grounds. It’s cool. I try to get after it as much as my body allows me to. Read the rest of this entry »

At the time of this writing, the Kansas City Royals’ playoff odds sit at 12%. They’re 54-55, 3.5 games back of the third AL Wild Card, packed in tight with a bunch of average teams chasing the major contenders, including the Rangers, Guardians, Rays, and Angels. (I’m going to go ahead and count the Twins out.) It’s a tough spot. You don’t necessarily want to go all in with a 12% chance of making the playoffs, but it’s a good enough shot that a sell-off would go down pretty poorly.

Threading this needle with precision, the Royals made a series of moves that filled key roster holes without gambling away any significant long-term pieces. The first of those went down yesterday morning, when they picked up two solid, controllable right-handers in Ryan Bergert and Stephen Kolek in exchange for backup catcher Freddy Fermin.

Later in the day, the Royals made two more trades. The first further shored up a depleted rotation; the second improved a truly abysmal outfield. First, they brought in lanky left-hander Bailey Falter from the Pirates, parting with up-and-down lefty Evan Sisk and Callan Moss, a first baseman with a .790 OPS in High-A who went undrafted in 2024. And a few minutes after the deadline passed, Jon Heyman reported that they’d picked up Mike Yastrzemski from the Giants for A-ball hurler Yunior Marte. Read the rest of this entry »

This, my friends, is the A.J. Preller we were promised. Mere hours after swinging a massive deal for closer Mason Miller and even fewer hours before trading for Ryan O’Hearn and Ramón Laureano, Preller made what you could argue – in one specific, absurd way – represented San Diego’s biggest upgrade of the day. Earlier this afternoon, ESPN’s Jeff Passan reported that the Padres have traded starters Ryan Bergert and Stephen Kolek to the Royals in exchange for catcher Freddy Fermin. How could Fermin, a 30-year-old catcher with roughly average framing numbers who’s underperforming his career 91 wRC+ this season, possibly be a bigger addition than Miller or O’Hearn, let alone worth the two major league pitchers the Padres gave up for him? Just you wait.

It would be hard to overstate both how ugly the catcher position has been for the Padres this season and how predictable that outcome was. Coming into the season, the Padres ranked dead last in our Positional Power Rankings at catcher. We expected them to get just 0.8 WAR from the catcher position, a hair behind the Rockies. And that was before our projections knew how bad things really were. Shortly after the those rankings came out, the Padres demoted Luis Campusano, who had the best projection on the team. Instead, they rolled with Elias Díaz and Martín Maldonado. (I’m sure the Padres have their reasons for being so out on Campusano, but I have no idea what they are. For what it’s worth, he has slashed .298/.410/.555 with 15 home runs in Triple-A El Paso this season, good for a 130 wRC+. In 27 PA as a designed hitter for the big club, he’s 0-for-21 with two walks, but even so, right now at this very moment, ZiPS sees him as the best catcher of the three.)

Díaz and Maldonado have caught every single inning for the Padres this season, and the results have been even worse than expected. (Following the initial publication of this piece, the Padres DFA’ed Maldonado.) Both players have put up negative WAR. Maldonado has a 62 wRC+, while Díaz is at 67. In all, the Padres have put up -0.6 WAR from the catcher spot, and the only reason that’s not the worst mark in baseball is that the Nationals spent the first half of the season challenging for the worst team catching season of the century. Things have been even worse lately, as Díaz has put up a 38 wRC+ in the month of July. Read the rest of this entry »

The weekend before the trade deadline was light on big names moving — poor Eugenio Suárez has probably had to take his phone charger out of his go bag a dozen times this month — but we did see plenty of preliminary action. The Orioles began their sell-off by shipping hard-throwing left-hander Gregory Soto up to the Mets. Meanwhile, the Royals sought to maintain their spot on the postseason wait list by picking up a right-handed bat from Arizona: not Suárez, but Randal Grichuk.

Finally, the Braves picked up some reinforcements for their injury-riddled rotation, tossing the Cardinals a player to be named later or cash in exchange for the right to jump the waiver line on recently DFA’d right-hander Erick Fedde. Read the rest of this entry »

There is a time in life when you expect the world to always be full of new things. And then comes a day when you realize that is not how it will be at all. You see that life will become a thing made of holes. Absences. Losses. Things that were there and are no longer. And you realize, too, that you have to grow around and between the gaps, though you can put your hand out to where things were and feel that tense, shining dullness of space where the memories are.

– Helen Macdonald

On Tuesday night, Rich Hill made his first major league start of the season and his first ever as a Kansas City Royal. Although he took the loss, the game lived up to its billing as a feel-good story. The 45-year-old lefty went five innings against the second-best offense in baseball, allowing one earned run and two unearned. He walked two Cubs, struck out one looking, induced 11 groundballs, and left the game with a 1.80 ERA. Stylistically, it was a vintage Rich Hill performance (from a vintage Rich Hill), featuring not-so-fastballs, loopy curves, and dropdown frisbee sliders. It was also a vintage Hill performance from a sensorial perspective, in that it involved a whole lot of strange human sounds.

I mentioned Hill’s vocalizations when I wrote about the minor league deal he signed with the Royals back in May. They’re right there in my mental map of a Hill start. But memory just can’t do justice to some things. It fades. It falters. Even the events that imprint upon us most deeply tend to loosen their hold with time. It’s cruel, but it’s for the best. If our memories could transport us exactly to who we were when we felt that first rush of puppy love, heard that one perfect song, tasted that one croissant in Paris, would we even bother to seek out new experiences, or would we just live within the old ones and keep playing the hits? All of this is to say that I thought I was prepared for the Rich Hill experience. I tuned into the game Tuesday night expecting to hear the man grunt. But then I actually heard the man grunt. I was not prepared. Read the rest of this entry »

At last we reach the end of my annual series spotlighting the weakest positions on contending clubs. While still focusing upon teams that meet that loose definition of contenders (a .500 record or Playoff Odds around 10%), I’ve also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance is worth a look.

At the other positions in this series, I have used about 0.6 WAR or less thus far — which prorates to 1.0 WAR over a full season — as my cutoff, but for the designated hitters, I’ve limited the list to the teams below zero, both to keep the length manageable and to account for the general spread of value. In the fourth full season of the universal DH, 0.6 WAR represents the median, with 10 teams below zero, 11 between zero and 1.0, and eight with 1.0 or more, with only four of those eight reaching 2.0. By comparison, at this time last year, half the teams in the majors were at 0.0 WAR or less. DHs as a group have hit .239/.322/.422 for a 108 wRC+ this season, the last of which matches 2024’s final figure.

It does appear that an increasing number of teams are investing more playing time in a single DH. From 2022 (the first full-length season with the universal DH) to ’24, the number of players reaching 450 plate appearances in the DH role increased from three to four to seven; this year, we’re on pace for 10. That said, many of the teams on this list are the ones that haven’t found that special someone to take the lion’s share of the plate appearances.

Today the Killers list turns the corner — or rather turns to the teams receiving less-than-acceptable production in the outfield corners. While still focusing on clubs that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 10%), and that have gotten about 0.6 WAR or less out of a position thus far (which prorates to 1.0 WAR over a full season), I’ve also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance is worth a look.

As noted previously, some of these situations are more dire than others, particularly within the context of the rest of their roster. I’ve batched the two corners into one supersized roundup because three of the seven teams below the WAR cutoff for left field also make the list for right field, and because there’s plenty of crossover in play with regards to personnel. The capsules are listed in order of their left field rankings first, while noting those crossover teams with an asterisk. As always, I don’t expect every team here to go out and track down upgrades before the July 31 deadline, but these are teams to keep an eye on.

Royals*

Good grief, somehow Royals corner outfielders have combined for -3.8 WAR, suggesting that the 47-50 team would be over .500 if it had found some typically unremarkable replacement level outfielders to fill those posts. Manager Matt Quatraro has used nine left fielders and eight right fielders, with some crossover between the two. Somehow, only one player at each position has managed even a 100 wRC+ in their thin slice of playing time, namely Jonathan India in left and Drew Waters in right. India, who’s played all of 21 games in left, is new to the position at the major league level; his glove is a liability no matter where you put him and he’s hitting just .251/.332/.348 (91 wRC+) overall. Waters, who’s played 41 games in left, 21 in right, and 22 in center, has hit just .243/.288/.316 (66 wRC+) overall, suggesting his 105 wRC+ in 53 PA in right is a fluke. Mark Canha has collapsed to a 49 wRC+ with career worsts in just about every key Statcast category, though his stints on the injured list for an adductor strain and (currently) tennis elbow have possibly contributed to his woes. None of the other principals at either corner has spent time on the IL.

Hunter Renfroe, who began the year as the regular right fielder, was a full win below replacement before he was released in late May. Jac Caglianone, a 22-year-old 50-FV prospect who has taken over right, has been the next-worst, at -0.9 WAR. Caglianone entered the season ranked no. 47 on our Top 100 Prospects list but had never played above High-A; he’s hit a cringeworthy .140/.196/.264 (22 wRC+) in 138 PA while chasing 41.1% of pitches outside the zone. At some point a responsible adult would send him back to the minors for more seasoning despite the occasional 466-foot homer. Instead, he’s 4-for-40 this month including that July 10 shot. Cool, cool.

In eight seasons of doing this series for FanGraphs (plus a handful of times at Baseball Prospectus and Sports Illustrated), I can’t recall even a fringe contender so hamstrung by an inability to find reasonably productive players at offense-first positions. It’s a testament to the quality of the Royals’ pitching and the play of Bobby Witt Jr., Maikel Garcia and Vinnie Pasquantino that this team even has a shred of a chance at a playoff spot. This is the part where I normally suggest potential trade targets who could help shore up the situation; in this case the answer is “just about anyone not already on the Royals roster.” Candidates such as the White Sox’s Andrew Benintendi and the Marlins’ Jesús Sánchez look like Juan Soto and Aaron Judge next to this crowd.

Reds*

Nothing the Reds have done with either outfield corner has worked for very long or very well. Manager Terry Francona has used 10 different left fielders and eight different right fielders, with six players getting time at both. Offseason acquisition Gavin Lux has logged a team-high 34 starts in left while bouncing around to make 30 more at DH, nine at second base, and five at third. Overall, he’s hit .265/.355/.379 (106 wRC+), but his play in left has been, uh, DH-caliber (-6 FRV, -4 DRS in 278.2 innings). Austin Hays, who’s split his time about equally between left (21 starts) and DH (23 starts), has been very effective when available (.287/.323/.517, 124 wRC+) amid three separate IL stints for left calf and left hamstring strains and a left foot contusion; he and Lux have generally shared the left field and DH roles against righties.

Jake Fraley has started 39 games in right, all but one against righties; he’s hit .224/.336/.376 (100 wRC+), but has served IL stints for a left calf strain and a right shoulder sprain, the latter of which he returned from just before the All-Star break. Will Benson has split his time between left (17 starts), right (22 starts), and center (three starts), with just four from that total against lefties; he’s scuffled to a .223/.276/.427 (87 wRC+) line. Of the eight other corner outfielders Francona has tried, only Santiago Espinal has a wRC+ of at least 100 in that capacity, but that’s over just 30 PA, and his overall 63 wRC+ factors into the Reds’ placement on the third base list.

With Hays and Fraley both healthy, the Reds are in better shape than they’ve been for most of the season; the pair has spent just about two weeks together on the active roster (the second half of April). Still, between those two and the everyday play of Lux at one position or another, they’re a bit light (spoiler alert: they’ll be on the DH list as well), with a right-handed bat probably their bigger need. Unlike the Phillies (below), they’re less inclined to add payroll, but as one of the league’s younger teams, they should think in terms of multiple years. Three righties who could be available, the Rangers’ Adolis García, the Orioles’ Ramón Laureano, and the Angels’ Taylor Ward, each have another year of club control remaining; the first two will be arbitration-eligible, the last has a $6.5 million option. Red Sox lefty Wilyer Abreu, who’s got one more pre-arbitration season, offers even more upside and control but will require a greater return.

Phillies*

As noted in Wednesday’s installment, the Phillies rank 27th in the majors in total outfield WAR at 0.3, with left field the weakest of the three positions. Max Kepler spent the better part of a decade as a league-average hitter with a good enough glove to be a two-to-three-win right fielder for the Twins, but last year, he made two trips to the IL and slipped to a 93 wRC+ and 0.9 WAR. The Phillies didn’t overcommit, signing him to a one-year, $10 million deal, but his offense has continued to lag. His 90 wRC+ (.210/.307/.371) is a career low, and in his first taste of left field — the easier of the two corners — his -2 FRV is as well. Kepler’s average exit velocity is about 2 mph higher than last year, with his barrel rate improving from 6.2% to 11.4%, and his hard-hit rate from 36.6% to 44.8%, but he’s fallen 51 points short of his .412 xSLG.

Right fielder Nick Castellanos needs no introduction to readers of this annual series. Four years into a five-year, $100 million deal with the Phillies, his timing remains impeccable: he’s landed here annually. His offense isn’t completely terrible for a change; his 107 wRC+ (.273/.313/.438) is in line with his final 2022 and ’23 lines, and only three points shy of the major league average for right fielders. Alas, he’s a DH stuck in the field because the Phillies already have a better DH in Kyle Schwarber. Castellanos’ defensive metrics are on track to be his worst since 2018; after averaging -9 DRS and -12 FRV in his first three seasons in Philly, he’s at -14 DRS and -12 FRV with 66 games to go.

The Phillies have recently given a bit of playing time in left field to 25-year-old rookie Otto Kemp, an undrafted free agent who hit .313/.416/.594 at Triple-A Lehigh Valley and is at .247/.316/.337 (86 wRC+) with a 28.6% strikeout rate through 98 PA thus far in the majors. Kemp has 30-grade contact skills due to his problems with secondary stuff, and his defense at third base, his primary position in the minors, is shaky. He might work as the short half of a corner platoon, but the Phillies really need to add a quality bat. Abreu, García, and Ward each offer some firepower (not necessarily without flaws), while Benintendi and Sánchez would at least raise the production floor.

Padres

Where have you gone, Jurickson Profar? A nation turns it’s lonely eyes to you… The departure of their 2024 left fielder left a hole that the Padres have tried to fill using 10 different player. The bygone platoon of Jason Heyward and Oscar Gonzalez wasn’t up to the task. What has worked lately, particularly on the offensive side, has been using Gavin Sheets in left. The ex-White Sock has hit .265/.324/.451 (119 wRC+) in 44 games at DH, 34 in left (with all but two of them coming since May 25), and 12 at first base. Historically, the 6-foot-3, 235-pound lefty has been brutal in right field (-23 DRS, -18 FRV in 1543 innings) but has been within one run of average in the two metrics in 263 innings in left thus far. He’s been light against lefties (96 wRC+, compared to 128 against righties), so he could use a platoon partner, particularly one who can also serve as a defensive replacement; neither Brandon Lockridge nor Bryce Johnson have shown themselves to be up to the task, but this shouldn’t be the hardest problem for A.J. Preller to solve at deadline time.

Dodgers

Michael Conforto’s one-year, $17 million deal flew under the radar this past winter given the team’s fancier expenditures, but like those, the early returns aren’t too hot. The 32-year-old Conforto has hit just .184/.298/.322 (80 wRC+) with eight homers and subpar defense in left field (-3 DRS, -3 FRV). July is his first month with a wRC+ of at least 100, albeit in just 38 PA, and there’s no underlying batted ball trend suggesting notable improvement. Indeed, Conforto’s Statcast contact numbers, while still above average, are down relative to last season, and he’s lagging well behind both his .243 xBA and .421 xSLG, with his 99-point shortfall in SLG the seventh-largest in the majors.

While the Dodgers have alternatives in left, Enrique Hernández figures in the third base picture with Max Muncy sidelined, and Andy Pages — whose 205 wRC+ in 44 PA is propping up the offensive numbers here — is better used in center or right. One as-yet unexplored option would be to add rookie Dalton Rushing to the mix. The 24-year-old backstop has hit just .221/.293/.309 (73 wRC+) since debuting in mid-May, but a weekly diet of 10 PA can’t be helping his cause, and he does have 33 games of minor league experience in left.

It’s not inconceivable that the Dodgers cut bait on Conforto, particularly if they have a roster crunch. But so long as their offense is scoring a major league-high 5.33 runs per game, the matter is less urgent than their perennial need for pitching amid so many injuries.

Astros

The Astros haven’t entirely buried the Jose Altuve experiment yet, but the 35-year-old star has started just two of Houston’s last 19 games in left (and 39 overall) compared to four at designated hitter and 13 at second base. His offense (.277/.336/.465, 121 wRC+) has been fine, but his defense at the new position has been brutal (-8 DRS, -4 FRV in 325 innings), and it’s been no picnic at second either (-3 DRS, 0 FRV in 263 innings). His best position these days is probably DH, and with Yordan Alvarez sidelined due to inflammation in his right hand with no clear return date, that option is at least open.

Of the eight other Astros who have played left, the best on both sides of the ball has been Mauricio Dubón, who’s made more starts at second than left (29 versus five) while also filling in at shortstop (where he’s helped to cover for the loss of Jeremy Peña to a broken rib), third, and the other two outfield spots. He’s hitting a comparatively robust .255/.292/.415 (96 wRC+) overall and is, of course, a better defender than Altuve at either post, but he belongs at a position where he can best utilize those defensive skills. The Astro who’d merit a closer look is Zach Dezenzo, but the 6-foot-5, 220-pound rookie was recently transferred to the 60-day IL while recovering from a capsule strain in his left hand. He’s just 6-for-47 while playing left but is hitting .245/.321/.367 (96 wRC+), with a 16.4% barrel rate and a .440 xSLG offsetting his 33.9% strikeout rate. He’s eligible to return in August, so the Astros may push forward with their current jumble and hope he can help later. Still, with apologies to Cooper Hummel, Taylor Trammell, et al, this team needs a garden-variety left fielder who can hit a lick and catch the ball.

Diamondbacks

Lourdes Gurriel Jr. is now in his third season as Arizona’s left fielder. While his .251/.299/.421 slashline represents drops of 28 points of AVG, 23 points of OBP, and 14 points of SLG relative to last year — for a 10-point drop in wRC+ (from 108 to 98) — his average exit velocity, barrel rate, and hard-hit rate are virtually unchanged, and his xBA, xSLG, and xwOBA have only fallen by six or seven points. Aside from a 4.5-percentage point drop in strikeout rate, resulting in more batted balls, nothing’s really changed for him on the offensive side. He’s on this list because of a bit of bad luck here and a dip in defensive metrics there (from 3 DRS to -6, and from 1 FRV to -2), but he’ll probably remain the everyday left fielder unless the Diamondbacks clear out some outfield depth and cut salary ahead of the trade deadline — in which case he could wind up with another team on this list.

Guardians

Originally drafted and developed by the Guardians, Nolan Jones made four Top 100 Prospects lists (2019–22) before being traded to the Rockies in November 2022. Following a strong rookie season in Colorado (20 homers, 20 steals, 137 wRC+, 3.7 WAR), he battled injuries — most notably a lower back strain — and struggled in 2024, hitting just .227/.321/.320 (69 wRC+) with three homers. The Guardians reacquired him in March and have generally started him against righties either in right (45 times) or center (12 times), with nine starts against lefties spread across the three outfield positions. Unfortunately, the lefty-swinging 27-year-old’s offense hasn’t returned; he’s batting just .229/.319/.330 (87 wRC+), though as noted in the center field installment, he’s hitting the ball harder than those results suggest, with a 91.5-mph average exit velocity (3.3 mph higher than last year), an 8% barrel rate, and a 46.3% hard-hit rate. He’s cut his groundball rate, is pulling the ball more often, and has even shaved his strikeout rate to 26.5%. The 95-point gap between his .425 xSLG and his actual mark is tied for the majors’ ninth-largest.

Jones could use some better luck and a better supporting cast. Jhonkensy Noel plummeted from last year’s 118 wRC+ to zero — yes, a 0 wRC+ — with a .140/.162/.215 slashline, earning him a ticket back to Triple-A Columbus. Current platoon partner Johnathan Rodríguez has been only slightly better (.140/.189/.220, 12 wRC+). Given their 46–49 record and other trouble spots (including shortstop and center field), the Guardians may wind up selling or holding, but one trade candidate who would make sense is Laureano, who spent parts of 2023 and ’24 with the team. The Guardians did release him last May, but his 135 wRC+ for the Braves and Orioles since then suggests he’s worth another look.

Mariners

The early-April loss of starting right fielder Victor Robles to a fracture of the humeral head in his left shoulder cost the Mariners a valuable catalyst. Luke Raley took over the position, but he strained his oblique in late April, missed seven weeks, and upon returning took over the long half of a first base platoon. Leody Taveras came and went. Fortunately for the Mariners, Dominic Canzone arrived from Triple-A Tacoma and has more or less saved the day. The 27-year-old lefty, who’s closed up his stance somewhat and is swinging the bat harder, has hit a sizzling .319/.340/.564 (158 wRC+) in 97 PA. Yes, he’s chasing nearly 38% of pitches outside the zone and walking just 3.1% of the time, but he’s also barreling the ball 15.6% of the time, and both his .300 xBA and .564 xSLG are in line with his actual numbers. He’ll cool off eventually, but currently this doesn’t look like a serious problem for the Mariners, and there’s still hope that Robles can return in September to provide support.

Cardinals

Jordan Walker entered the 2023 season as a 60-FV prospect ranked no. 12 on our Top 100 list, but in parts of three seasons, he’s produced diminishing returns, including a meager .210/.267/.295 (60 wRC+) with a 33% strikeout rate in 191 PA this season. He’s been largely absent from the lineup since late May, first missing a couple of weeks due to inflammation in his left wrist, then enduring a bout of appendicitis in late June. While on his latest rehab assignment, the Cardinals are again tinkering with his swing, but so far, he’s gone just 7-for-46, albeit with five extra-base hits, at Double-A Springfield and Triple-A Memphis.

Walker’s still just 23, but it’s fair to wonder if he’ll ever live up to that lofty prospect billing, at least in St. Louis. The good news for the Cardinals is that Alec Burleson has taken over right field and absolutely raked, hitting .333/.374/.592 (158 wRC+) in 138 PA. Overall, the 26-year-old lefty has hit .293/.340/.466 (125 wRC+), though he could use a platoon partner; he has a career 52 wRC+ against southpaws.

Twins

Matt Wallner can mash. In 2023 and ’24 combined, he hit .254/.371/.515 (148 wRC+) with 27 homers in 515 PA for the Twins, even while striking out a whopping 34% of the time and spending chunks of both seasons in Triple-A. The Twins hoped that he could approximate that production across a full season, but a mid-April hamstring strain curtailed his strong start; he didn’t return until May 31 and has managed just a 91 wRC+ since. His overall line (.205/.299/.449, 107 wRC+ with 10 homers) in 41 games in right and 12 at DH rates as a disappointment. He’s getting under too many balls; his 21.8% infield fly ball rate is the second-highest of any player with at least 150 PA. Trevor Larnach, who covered right for part of Wallner’s absence and has lately been sharing the job, has hit a modest .245/.311/.415 (102 wRC+) while playing 34 games in right plus another 59 at DH and in left field. Willi Castro, the only other Twin with at least 20 PA as a right fielder, has struggled in his time there (28 games but just 15 starts) but has hit for a 124 wRC+ overall in his utility role.

Considering this is now the fifth position at which the Twins have made a Killers list, it’s clear they’ll have to solve some problems from within in order to challenge for a playoff spot. Despite his struggles, Wallner’s recent track record provides more reason for optimism than, say, Ty France at first base.
