On June 30, the Rangers lost to fall to 41-44, 10th place in the American League. Then they turned it on. Since the calendar flipped to July, they’ve gone 16-8 and rocketed into the playoff picture. They’re tied with the Mariners for the last AL Wild Card spot. With their sights now set on thriving in October, they needed to reinforce a pitching staff that has been quite good up top but got shakier as you went down the depth chart, and the Diamondbacks were happy to oblige. As Ken Rosenthal first reported, the Rangers are getting Merrill Kelly in exchange for Kohl Drake, Mitch Bratt, and David Hagaman. They also acquired Danny Coulombe and Phil Maton in separate deals to shore up the middle of their bullpen.
Texas has a famous starting rotation. The two stars, Jacob deGrom and Nathan Eovaldi, need no introduction. Second on the team in innings, slightly ahead of Eovaldi? That’d be World Series winner Patrick Corbin, famous both for his high highs and low lows. The back of the rotation? Jack Leiter and Kumar Rocker, famous college teammates before they were famous prospect teammates. But Leiter and Rocker have been flat this year, and Corbin was bad enough for long enough that I’d be a little scared of counting on him. Tyler Mahle, another celebrated Rangers starter, has been out since June. Jon Gray is headed for free agency and has perhaps been banished to the bullpen for the remainder of 2025. And it’s not like deGrom has been the paragon of health over the last few years.
Kelly lengthens the playoff-ready portion of Texas’s rotation immediately. His career 3.74 ERA and 3.97 FIP are accurate representations of his work, as are his 22% strikeout rate and 7.4% walk rate. In other words, he’s a perfect mid-rotation arm, better than average (he’s managed a 3.22 ERA and 3.53 FIP this season) but squarely short of an ace. He’s 36 and a free agent after this year, which limits his return somewhat, but he’s a dependable playoff starter and thus a very desirable deadline target. Read the rest of this entry »
It’s a big deadline for relief pitchers, even for teams that aren’t operating in the Mason Miller or Jhoan Duran tier. The Orioles bullpen continues to get picked over like a charcuterie board: Andrew Kittredge is Chicago-bound, with the Cubs sending Wilfri De La Cruz the other way.
The Tigers beefed up their bullpen by picking up Paul Sewald from the Guardians in exchange for a player to be named later or cash. A few hours later, Detroit sent minor league pitchers Josh Randall and R.J. Sales to Washington for Kyle Finnegan and added Codi Heuer from Texas for minor league depth. Finally, the Dodgers are bringing Brock Stewart back from Minnesota, with James Outman going in the other direction.
Tyler Mahle was 23 years old and had 20 big league innings under his belt when our 2018 Cincinnati Reds Top Prospects list was published in January of that year. A seventh-round pick out of an Orange County high school five years earlier, Mahle was ranked fourth in the system, with Eric Longenhagen assigning him a 50 FV.
Mahle has gone on to have an injury-marred career. Most notably, he underwent Tommy John surgery in May 2023, less than a year after he’d been dealt from the Reds to the Minnesota Twins in exchange for Christian Encarnacion-Strand, Spencer Steer, and Steve Hajjar at the trade deadline.
When healthy, the 30-year-old right-hander has been a quality pitcher more often than not. In 2021, he made 33 starts for Cincinnati and went 13-6 with a 3.75 ERA and a 3.80 FIP over 180 innings. Moreover, Mahle was on track for an even better season when he went on the shelf seven weeks ago with what has since been diagnosed as a right rotator cuff strain. In 14 starts comprising 77 innings with the Texas Rangers, Mahle had a record of 6-3 to go with a 2.34 ERA and a 3.37 FIP. His status for the remainder of the current campaign is unclear.
What did Mahle’s 2018 FanGraphs scouting report look like? Moreover, what does he think about it all these years later? Before he went on the injured list, I shared some of what Eric wrote and asked Mahle to respond to it.
———
“After 24 hyper-efficient starts at Double and Triple-A, Mahle finally got a four-start cup of coffee in Cincinnati at the end of the season. His ability to locate was not on display in the big leagues, but it’s what got Mahle there.”
“Not great,” Mahle said of his four starts in 2017. “I was wild. My first two or three starts, I’d thrown something like 50 pitches by time I got through two innings. So yeah, not very efficient. But I got through it. Then I got off to a decent start the next year, in 2018, but pitched kind of hurt toward the end of that season.”
“He has above-average fastball command despite a somewhat noisy delivery; it should tighten another half-grade as Mahle hits his peak.”
“Hmm… yeah, my delivery back then was super stiff,” he said. “I held my glove up high and it stayed there until I broke my hands. Looking back, my delivery was, again, super stiff. A lot has changed there.
“Honestly, I don’t remember exactly,” Mahle said when asked when he made the adjustment. “It must have been with [Reds pitching coach Derek Johnson]. We kind of took away some movement in the hands. Instead of going from up high to down low, we started going from the belt to make it a little simpler.”
“His stuff is middling, spearheaded by a slightly above-average fastball/slider combination out of which Mahle squeezes every ounce of juice due to his ability to locate.”
“I was pitching with pretty much all fastballs at that time,” the righty recalled. “My slider was super inconsistent. I didn’t have a splitter like I have now. I basically just relied on the fastball.”
“He adds and subtracts from his fastball, exhibiting velocities anywhere from 88 to 95, touching 96 regularly, and maxing out at 98.”
“Yeah, but not so much anymore,” Mahle admitted. “I kind of live low 90s now and will top around 95. But relying so much on my fastball back then, I had to try to overpower guys with it. I had to try to throw it hard.”
“While Mahle’s change doesn’t have terrific movement, his ability to manipulate pitch speed without noticeable arm deceleration helps make it a viable third offering.”
“Yep. I mean, that was me,” Mahle said. “I didn’t have much of a changeup, so I had to try to place it in the zone, or wherever I was trying to get it. Like my slider, it was just super inconsistent. The arm speed… I actually feel like I probably did have to change it, based on what I was throwing. I maybe telegraphed a lot back then. Now I can throw everything with pretty much the same arm speed.”
“His stuff isn’t overwhelming, but his command should allow him to survive as an average big league starter.”
“That’s how I’ve gotten by,” the nine-year veteran acknowledged. “My command, still now… like, my fastball isn’t an overpowering pitch velo-wise, but I locate it. I also get some good ride on it. Back then, I didn’t know that. I just knew that it did well up in the zone. But yeah, I kind of lived off the location of my pitches.
“I understand everything a lot more now,” Mahle added. “I know why it works well up in the zone, and what the separation is on each pitch, and why they’re doing what they’re doing. Compared to now, back then I was pretty much just throwing.”
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.
In a race for a playoff spot, every edge matters. Yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing mediocre production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book, It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement-Level Killers. I’ve revisited the concept numerous times at multiple outlets and have adapted it at FanGraphs in an expanded format since 2018.
When it comes to defining replacement level play, we needn’t hew too closely to exactitude. Any team that’s gotten less than 0.6 WAR from a position to this point — prorating to 1.0 over a full season — is generally in the ballpark, though my final lists also incorporate our Depth Charts rest-of-season projections, which may nose them over the line. Sometimes, acceptable or even above-average defense (which may depend upon which metric one uses) coupled with total ineptitude on offense is enough to flag a team. Sometimes a club may be well ahead of replacement level but has lost a key contributor to injury; sometimes the reverse is true, but the team hasn’t yet climbed above that first-cut threshold. As with Supreme Court Justice Potter Stewart’s definition of hardcore pornography, I know replacement level when I see it. Read the rest of this entry »

Coming into 2025, you might not have expected Alejandro Kirk and Ernie Clement to play central roles on a playoff contender. Neither player was an above-average hitter last season; in fact, each hit for a 93 wRC+ while playing regularly for a team that won just 74 games. Yet the pair rank first and second in position player WAR on the Blue Jays, thanks not only to improved offense but exceptional glovework, with Kirk battling the Giants’ Patrick Bailey for the top spot in two catching metrics, and Clement ranking among the best third basemen while also posting strong metrics in limited duty at the three other infield positions. The pair have not only helped the Blue Jays to a 47-38 record and the top AL Wild Card position, but also the top ranking in my annual midseason defensive breakdown.
Kirk and Clement aren’t Toronto’s only defensive stalwarts. Second baseman Andrés Giménez and center fielder Myles Straw, a pair of light-hitting glove whizzes acquired from the Guardians in separate trades this past winter, have been strong at their respective positions, with the latter helping to cover for the absences of Daulton Varsho. A Gold Glove winner last year, Varsho missed the first month of this season recovering from right rotator cuff surgery, and returned to the injured list on June 1 due to a strained left hamstring. Even in limited duty, Straw, Varsho, and Giménez — who missed about four weeks due to a quad strain, with Clement filling in at second for most of that time — have all rated as three to five runs above average according to Statcast’s Fielding Runs Value (FRV), and five to eight above average according to Defensive Runs Saved (DRS). Clement has totaled 12 DRS and 10 FRV at the four infield spots; in 359.2 innings at third, he’s second in the majors in both DRS (7) and FRV (5).
This is the third year in a row I’ve taken a midseason dip into the alphabet soup of defensive metrics, including Defensive Runs Saved (DRS), Statcast’s Fielding Run Value (FRV), and our own catcher framing metric (hereafter abbreviated as FRM, as it is on our stat pages). One longtime standby, Ultimate Zone Rating (UZR), has been retired, which required me to adjust my methodology. Read the rest of this entry »
Below is an analysis of the prospects in the farm system of the Texas Rangers. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.
A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.
All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Any fan, analyst, or baseball executive would be hard-pressed to say that the Rangers pitching staff has failed to do its job in 2025. The rotation has been especially solid, ranking first in baseball in ERA, seventh in FIP, and sixth in WAR. If the bullpen hasn’t been as dominant, they’ve also improved significantly compared to last season, already accumulating almost as many wins above replacement as they did in the entire 2024 season. And yet the Rangers, less than two years removed from soaking each other with champagne to celebrate a World Series championship, sit below .500. A losing season here would be the franchise’s eighth in the last nine years, its worst showing since the move from Washington to Texas. The bats have let the team down, ranking near the bottom of baseball, and what’s worse, the underperforming offense consists mainly of players who the Rangers wanted in their lineup. So is there hope for a turnaround, or will the Rangers need to find new solutions to their run-scoring woes?
First, let’s assess just how lousy the offense has been. Well, ranking 25th in the majors in runs scored is their sunniest number. The Rangers rank 28th in on-base percentage, 27th in slugging percentage, and 28th in wRC+ at 80. The latter number outpaces only the Pirates and Rockies, two teams you don’t especially want to model your ballclub after. While the team has played solid defense, the abundance of leather hasn’t come close to making up for the shortage of wood, leaving the Rangers’ position players 25th in the league in WAR. What little offense there has been has come in very short bursts:
Mikey Romero has hit a few speed bumps since the Boston Red Sox drafted him 24th overall in 2022 out of California’s Orange Lutheran High School. A back injury limited the 21-year-old multi-position infielder to just 34 games in 2023, and he then didn’t return to game action until last May. He also missed time in August after suffering a concussion.
When healthy, it’s been mostly smooth sailing for the former first-rounder. [Boston took Roman Anthony 16 picks later the same year]. Romero’s last-season ledger included 16 home runs and a 125 wRC+ over 362 plate appearances between High-A Greenville and Double-A Portland.
He’s off to a strong start in the current campaign. Back at the higher of those levels, Romero is swinging to the tune of a 134 wRC+ in 154 trips to the plate. Fully half of his 34 hits have gone for extra bases. The San Diego native’s smooth left-handed stroke has produced 10 doubles, a pair of triples, and five home runs.
As the season was getting underway, I asked the promising youngster how he’s grown as a hitter since joining the professional ranks. Read the rest of this entry »
Way, way, way back in December 2023, the Rangers signed Tyler Mahle to a two-year contract. Absolutely nobody cared at the time, mostly because the news dropped the same day as Shohei Ohtani’s first press conference with the Dodgers. But also because Mahle, then recovering from Tommy John surgery, was expected to play a trivial part, at best, in the 2024 season.
Mahle had been a bit of a hipster favorite as an upper-mid-rotation starter in Cincinnati and then briefly in Minnesota — far from a household name, but from 2020 to 2022, he’d been quite good, and in high volume. Over those three seasons, he’d averaged 27 starts, 146 innings, and 3.0 WAR per 162 team games, with an ERA- of 90. For two years and $22 million, the Rangers were conceding that he’d rehab on their dime for most of 2024. But he would’ve been available for the 2024 playoffs if they’d made it that far, and if everything worked according to plan, they’d have a workhorse no. 3 starter under contract for 2025 at a fraction of what that kind of production usually goes for.
At least in 2025, everything has been working according to plan. Mahle has made 11 starts so far this season, with the past 10 lasting at least 80 pitches and five innings. Until his most recent outing, he hadn’t allowed more than two runs in any start. Even then, he allowed only three runs in his season-worst outlier. His 1.80 ERA is fifth best among all qualified starters. Read the rest of this entry »
