Whit Merrifield has long been one of the best base stealers in the game, but he has seemingly reached a new level of thievery this season, with 33 steals on only 35 attempts. That 94% success rate is the highest of his career and leads the majors among players with at least 20 attempts (Bo Bichette is an impressive 17 for 17). Our base running metric pegs him as the most valuable runner in the game, and he’s on pace to set a new career high in steals (he swiped 45 in 2018) with a chance to become the first player to reach 50 steals since 2017 — and all at the age of 32.

What’s particularly interesting is that, despite a 90th percentile Sprint Speed of 28.7 feet per second, which is about a half a foot per second off of his peak, Merrifield is far from elite when it comes to his short distance split times, which is a good way to gauge a player’s acceleration. His 90-foot split has gone from a peak of 3.89 seconds in 2018 to 3.97 this season, or from the 79th percentile to the 68th. Other elite thieves like Trea Turner, Byron Buxton and Tim Locastro have splits in the 99th percentile. Even Starling Marte, a fellow high success-rate stealer in his early 30s, is in the 81st percentile.

Base stealing is much more than a runner going top speed, though; it’s a mental and physical duel between the base runner and the pitcher. (That’s not to make light of the catcher’s role, but they are often left holding a baton, and the blame, for a race long lost.) What makes Merrifield the best base stealer in the game at a time when he’s far from the fastest player in the game is that he’s a master of this duel.

When Nicky Lopez steps to the plate, there is no in-between to his game. Of the 315 players who have seen at least 1,000 pitches over the past two seasons, Lopez places 27th in swinging strike rate (7.5%), in the top third in chase rate (24.7%), and in the top quarter in terms of the percentage of pitches put into play (18.8%) (all stats are through games on August 10). He combines elite plate discipline with an uncanny knack for making contact, an unusual mix of skills in the majors today. Players tend to make a trade-off when choosing to be more selective by accepting that they will put fewer balls in play. Balls in play have about a 178-point wOBA advantage over plate appearances that end in a walk or strikeout. But balls in play on pitches outside of the strike zone only enjoy a 97-point advantage over the combination of walks and strikeouts, a much less enticing proposition. Thus, by avoiding swinging at pitches outside the zone, hitters maximize their chances of putting a high-value batted ball into play, but also lengthen the plate appearance and increase the chance they strikeout. Lopez does not make this tradeoff, as you can see below:

I referenced Lopez’s minuscule 7.5% swinging strike rate; as a percentage of the total number of pitches he has seen, he rarely swings and comes up empty. He either makes contact or doesn’t swing at all. And the rate at which he swings at pitches overall is another indication of his selectivity. Over the last two seasons (2020-21), he’s swung at just 44.2% of the pitches he has seen, 2.9 percentage points less than the rest of the league over that sample.

Selectivity is great if you make it count when you do swing and put the ball in play on those pitches more towards the heart of the zone. Lopez’s problem, especially in his 2019 debut and last season, is that he often hasn’t reaped the benefits of his patience. This is the other side of his game. He has posted barrel rates in the second, fourth, and first percentiles and hard-hit rates in the second and sixth percentiles in his three seasons in the big leagues. He has also yielded zone run values per 100 pitches of -4.44, -5.17, and -3.02 in those seasons, compared to 1.86, 2.30, and 2.97 on pitches out of the zone, a product of his excellent approach but lack of punch when pitchers challenge him (average is 2.10 for out of zone and -2.21 for in zone). His career wOBAcon on the balls he puts in play inside the strike zone is just .302, 101 points lower than the league over that span. Through 937 major league plate appearances, he has hit three home runs, none of which have come in 2021. His extreme lack of pop has manifested itself in a 56 and 55 wRC+ in 2019 and ’20, respectively, the latter of which was also a product of his in-zone contact rate cratering to 82.4%. That placed him in the 51st percentile in 2020, not nearly high enough to offset the types of balls he puts into play. Read the rest of this entry »

As a shortstop, you never want to be in this position:

You can almost see the expletives flying out of his mouth, and it gets worse: Nolan Arenado is out of frame to the right, which means that ball is ticketed for left field. How did it get to this point? Let’s back up.

When you’re fielding a bunt, decisions come at you immediately. Barehand it? Glove it? Lead runner? Take a beat and take the sure out? You have to make all of those choices in a split second. Here’s the play in the ninth inning of Sunday’s Cardinals/Royals game that left Paul DeJong lunging helplessly:

Obviously, it didn’t turn out well. But it’s not as though Paul Goldschmidt didn’t know there was a chance of failure going in. Going for the lead runner on a bunt is a high-risk, high-reward play; anyone could tell you that. How large was the risk? How valuable was the reward? Let’s find out together, because I think this situation is low-key fascinating. Read the rest of this entry »

These are notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments of the Daily Prospect Notes here.

Emiliano Teodo, RHP, Texas Rangers
Level & Affiliate: Arizona Complex League Age: 20 Org Rank: 25 FV: 40+
Line: 3 IP, 1 H, 0 BB, 0 R, 2 K

Notes
Like Daniel Palencia (now of the Cubs, formerly of the A’s), Teodo signed just before the 2020 season that never happened and only popped onto the radar screen in 2021, when we actually had consistent minor league activity on the backfields. He’s been parked in the 98-101 mph range and spins in an upper-70s curveball that’s at times in excess of 3,000 rpm. Skinny and featuring a fairly violent delivery, Teodo’s projection skews toward relief, but there’s ample time to develop him because of when he signed. He’s another high-variance/upside arm in the Rangers system. Read the rest of this entry »

The trade deadline has come and gone, and teams are approaching the two-thirds mark of the season. With the elimination of August waiver season, clubs have little room to adjust from here. Other than the smallest of moves involving minor leaguers or unaffiliated players, rosters are what they are, and evaluators have already moved on to preparing for the offseason free agent class. In some ways, it’s a frustrating time for playoff contenders, as one can feel a bit helpless; all you can do from here on out is watch what happens. For teams clearly out of the playoff race, August and September have a different dynamic, with clubs using their last 60 games to learn about their young players. There is no greater jump in baseball than from Triple-A to the big leagues. The players are exponentially better, and there are prospects who thrive (or shrink) in ballparks with third decks, bright lights, and an army of TV cameras. In terms of the 2021 season, the teams listed below are playing out the string. But they’re also using this time to figure out which of the players on their roster can be part of their next team to play late-season games that matter.

Arizona Diamondbacks

The Diamondbacks had a relatively quiet deadline, but this also wasn’t a team expected to be this bad or loaded with good players on expiring deals. It will be interesting to see if Cooper Hummel, acquired from Milwaukee in the Eduardo Escobar deal, gets some major league at-bats this year. He’s had an outstanding Triple-A campaign, with more walks than strikeouts and a decent amount of power, but he also turns 27 in November, so it’s time to get going. It’s interesting to note that Arizona tried him at third base (it was just his second game at the position as a pro) during his first week in Reno, as most scouts put him firmly in the 1B/LF category. It looks like the D-backs will initially give at-bats to another older minor league slugger in the form of Drew Ellis, with the hope that one of the pair can represent an improvement over Christian Walker, which wouldn’t be asking much. The club also needs more assurances from Pavin Smith and Daulton Varsho, who so far have both looked more like nice bench pieces than everyday players on a contending team. A remarkable 36 players have taken the mound for the Diamondbacks, but the majority of their better pitching prospects are at the lower levels, so all they can really do from here is keep rolling out a variety of Quad-A-type bullpen arms to see if any of them have potential beyond that.

What a ride this year’s deadline was. All told, we had 75 prospects move in the last month. They are ranked below, with brief scouting reports written by me and Kevin Goldstein. Most of the deals these prospects were a part of were analyzed at length on this site. An index of those pieces can be found here, or by clicking the hyperlink in the “Trade” column below. I’ve moved all of the players listed here to their new orgs over on The Board, so you can click through to see where they rank among their new teammates. Our farm rankings, which now update live, also reflect these changes, so you can see where teams’ systems stack up post-deadline.

A couple of quick notes before I get to the rankings. We’ve included a few post-prospect players here (those marked in blue) so you can get an idea of where we value them now as opposed to where we had them at their prospect peak. Those players, as well as the Compensatory pick the Rockies will receive after they extend Trevor Story a qualifying offer and he signs elsewhere, are highlighted below. We had closer to 40 prospects (and 23 Players to be Named Later) traded last year, with the PTBNL number inflated by 2020’s COVID-related transaction rules. The backfields are not well-represented here, with just four prospects who have yet to play in full-season ball. Two of those are currently in the DSL and have no official domestic pro experience, though Alberto Ciprian has played stateside for instructs/extended spring training. Now on to the rankings.

The Braves have added an entire outfield in one deadline day. They swung two deals earlier on Friday, one with Cleveland and one with Miami, helping them set up a left-field platoon of Eddie Rosario and Adam Duvall. But they made an even bigger splash just prior to the buzzer with a one-for-one deal with the Royals, acquiring Jorge Soler from Kansas City in exchange for righty Kasey Kalich.

Soler is a huge name on paper, but he’s in the midst of a major down year. He’s pretty much your typical big-power, swing-and-miss outfielder, but a deflated BABIP at just .229 and a below-career-norm ISO at .179 have contributed to an uncharacteristically low .192/.288/.370 triple slash, good for a 81 wRC+. He’s still slugged 13 homers, but the lack of production at the plate — in combination with poor defense in right field and half of his starts coming at designated hitter — has yielded an ugly overall output. Soler has been worth -1.0 WAR, the fourth-lowest mark among all position players.

Still, there’s plenty of reason to think that Soler’s 2021 is something of an anomaly. He’s hitting the ball hard — his average exit velocity and hard-hit rates are both in the 91st percentile — and he’s still hitting the ball in the air, with a 17.3 degree average launch angle and just a 39.7% ground ball rate, a touch below his career averages. Perhaps he is hitting too many popups though, as the percentage of batted balls he’s “under” has risen to his highest level since 2017, before his breakout. Perhaps that is still a bit nit-picky for someone who has seemingly just been dealt a lot of poor luck; Soler’s expected wOBA is still roughly in line with his 2020 figure, and the disparity between his expected and actual wOBAs is the fifth-largest in the game.

At the start of the season, the Dodgers had so much pitching depth it was a legitimate question as to how they would effectively use all of their talent. But what was a source of strength for Los Angeles in March has become a reason for cautious concern in July, as the team lost Dustin May to Tommy John surgery in early May and Clayton Kershaw to elbow inflammation in July. In the bullpen, meanwhile, Corey Knebel was lost on April 24 to a lat injury, Scott Alexander went on the IL for a second time on July 20 with left shoulder inflammation, and Joe Kelly is day-to-day with a hamstring injury. The Dodgers shifted Tony Gonsolin and David Price to the rotation to patch some of those holes, but while that pair’s been mostly effective as starters, that’s come at the expense of bullpen depth.

The bottom line is that the Dodgers probably needed to bolster their pitching staff, and that’s been the case since even before Trevor Bauer was placed on administrative leave while MLB and the Pasadena Police Department investigate disturbing charges of sexual assault. His latest hearing was postponed until at least August 16, and MLB has extended his administrative leave until at least August 6; it’s an open question at this point if he’ll pitch again this season (or for Los Angeles).

So with 36 hours until the deadline, the Dodgers made a deal with the Royals to replenish some of that depth with injured veteran Danny Duffy, who is in the final year of his contract and could work as a middle reliever or spot starter. Given his nature as a rental, the two teams will settle on player(s) to be named later from a pre-approved list, with Los Angeles also getting some cash back from Kansas City.

The trade deadline is nearly here and once again, team behavior will be driven, at least in part, by 40-man roster dynamics. Teams with an especially high number of both rostered players under contract for 2022 and prospects who would need to be added to the 40-man in the offseason have what is often called a “40-man crunch,” “spillover,” or “churn,” meaning that the team has incentive to clear their overflow of players by trading for something they can keep — pool space, comp picks, or, more typically, younger players whose 40-man clocks are further from midnight — rather than do nothing, and later lose players to waivers or in the Rule 5 draft. In an effort to see whose depth might augment trade behavior, I enjoy assessing clubs’ 40-man futures every year. This exercise is done by using the RosterResource Depth Chart pages to examine current 40-man occupancy, subtracting pending free agents (on the Team Payroll tab), and then weighing the December 2021 Rule 5 eligible prospects to see who has the biggest crunch coming and might behave differently in the trade market because of it.

Some quick rules about 40-man rosters. Almost none of them contain exactly 40 players in-season because teams can add a player to the 40 to replace a player who’s on the 60-day Injured List. In the offseason, teams don’t get extra spots for injured players and have to get down to 40, so if they want to keep some of the injury fill-ins, they have to cut someone from the 40-man to make room.

In November, clubs have to add prospects to the 40-man to protect them from the Rule 5 draft. RosterResource is the most accessible resource for tracking the prospect timelines. Most teams add a handful of players every offseason, while some add just one, and others may add as many as 10. Read the rest of this entry »

The Learning and Developing a Pitch series returned last month after being on hiatus due to the pandemic. Each week, we’ll hear from three pitchers on a notable weapon in their arsenal. Today’s installment features a southpaw, Damon Jones, and a pair of right-handers, Zach McCambley and Josh Staumont, on their curveballs and sliders.

Damon Jones, Philadelphia Phillies prospect

“My slider is kind of seam-shifted. I get a lot of horizontal — something like 23 inches, which is pretty crazy — and I kind of picked it up off a Pitching Ninja video. It was Trevor Bauer’s grip, but I changed it up a little bit. It was more my thumb. I left the fingers how he had them, but he touches his thumb and I kind of hook it on the bottom part of the horseshoe. I think that helps the ball come out of my hand a little bit later. Watching the video, he wanted to get it out early and let it spin. I want it to be more of a late, back-foot pitch. The more I can make it look like a fastball the better, and it’s been pretty similar for me in terms of release point, release height, and all that.

“This was in 2019 — I made the jump from High-A to Triple-A that year — and it was shortly after spring training. After my first or second start in High-A, I was toying with stuff, saw the grip, and started throwing it. The guy on the Rapsodo was like, ‘Can you repeat that pitch? Can you do it again?’

“Then, when I got to Double-A, Tommy Hunter was rehabbing with us. He told me, ‘It’s like an Andrew Miller type of slider, it’s just wipeout.’ I was like, ‘Well, he’s got a lot of showtime and has seen a lot of guys with good sliders, and he’s comparing me to the guy Andrew Miller was when he was in his prime.’ I was like, ‘I’ll take that.’ Read the rest of this entry »
