Coming into 2025, you may not have anticipated Alejandro Kirk and Ernie Clement to play central roles on a playoff contender. Neither participant was an above-average hitter final season; in actual fact, every hit for a 93 wRC+ whereas enjoying recurrently for a staff that received simply 74 video games. But the pair rank first and second in place participant WAR on the Blue Jays, thanks not solely to improved offense however distinctive glovework, with Kirk battling the Giants’ Patrick Bailey for the highest spot in two catching metrics, and Clement rating among the many finest third basemen whereas additionally posting sturdy metrics in restricted obligation on the three different infield positions. The pair haven’t solely helped the Blue Jays to a 47-38 file and the highest AL Wild Card place, but in addition the highest rating in my annual midseason defensive breakdown.
Kirk and Clement aren’t Toronto’s solely defensive stalwarts. Second baseman Andrés Giménez and middle fielder Myles Straw, a pair of light-hitting glove whizzes acquired from the Guardians in separate trades this previous winter, have been sturdy at their respective positions, with the latter serving to to cowl for the absences of Daulton Varsho. A Gold Glove winner final yr, Varsho missed the primary month of this season recovering from proper rotator cuff surgical procedure, and returned to the injured record on June 1 as a result of a strained left hamstring. Even in restricted obligation, Straw, Varsho, and Giménez — who missed about 4 weeks as a result of a quad pressure, with Clement filling in at second for many of that point — have all rated as three to 5 runs above common based on Statcast’s Fielding Runs Worth (FRV), and 5 to eight above common based on Defensive Runs Saved (DRS). Clement has totaled 12 DRS and 10 FRV on the 4 infield spots; in 359.2 innings at third, he’s second within the majors in each DRS (7) and FRV (5).
That is the third yr in a row I’ve taken a midseason dip into the alphabet soup of defensive metrics, together with Defensive Runs Saved (DRS), Statcast’s Fielding Run Worth (FRV), and our personal catcher framing metric (hereafter abbreviated as FRM, as it’s on our stat pages). One longtime standby, Final Zone Ranking (UZR), has been retired, which required me to regulate my methodology.
On a person stage, even a full season of information isn’t sufficient to get the clearest image of a participant’s protection, and it’s by no means stunning that samples of 700 innings or much less produce divergent values throughout the main metrics. In spite of everything, they’re primarily based on differing methodologies that produce various spreads in runs from high to backside, spreads that owe one thing to what they don’t measure, in addition to how a lot regression is constructed into their techniques. Pitchers don’t have FRVs, and DRS tends to supply extra excessive scores (optimistic and adverse) than Statcast. However inside this aggregation, I believe we get sufficient sign at this level within the season to justify checking in. I don’t proclaim this to be a bulletproof methodology a lot as an excellent level of entry right into a broad matter.
A bit extra in regards to the methodology is so as. To account for all of the bits within the alphabet soup, I aggregated the aforementioned metrics, adjusting for the various spreads in run values through the use of customary deviation scores (z-scores), which measure what number of customary deviations every staff is from the league common in every class. As with final yr, I’ve damaged out catcher values for each FRV and DRS from the remainder of a staff’s values in each metrics. Word that the model of DRS that we show on FanGraphs now features a framing part (rSZ, for strike zone) that isn’t utilized in Baseball Reference’s WAR calculations (you’ll find it on a participant’s fielding web page). The three catcher measures (together with FRV) are every weighted at one-half the worth of the non-catcher scores, which improves the general z-score components’s correlation with run prevention. New for this yr, I’m utilizing Defensive Effectivity, the speed at which a staff turns batted balls into outs, revealed at Baseball Reference. I initially weighted that equally with non-catcher DRS and FRV, however discovered that weighting it at 1.5 occasions improved the correlation with run prevention. Final yr’s midseason z-score components had a -.39 correlation with runs allowed per sport (larger scores imply fewer runs allowed), however with this yr’s reconfigured components, the correlation has improved to -.75.

All statistics by means of June 29. Yellow = Prime-three rating in class (together with ties). Blue = Backside-three rating in class (together with ties).
What follows is a better have a look at the highest six groups by this ranking. Since writing in regards to the bottom-ranked groups quantities to taking pictures fish in a barrel, I’ve chosen to bypass that one. As an alternative, I’ll have a companion article overlaying the contenders with the weakest defenses someday earlier than the July 31 commerce deadline.
Blue Jays
Toronto is the runaway chief, with greater than a full level separating the staff from the remainder of the pack; the gap between the Blue Jays and the second-place Braves is about the identical as that between the Braves and the sixth-place Tigers, or the sixth-place Tigers and the ninth-place Giants.
The tandem of Kirk and backup Tyler Heineman helps the Blue Jays dominate the catcher-based rankings; they’re among the many high three in all three classes. Kirk (in 521 innings) leads the majors in FRV (14 runs), with a share of the lead within the every of the three classes it covers: framing (8), blocking (3), and throwing (3). He’s additionally second in FRM (6.4), and is tied with Heineman (in 209.2 innings) for fourth in DRS (6).
Together with the excellence of Straw and Varsho in middle — the pair has mixed for 14 DRS and eight FRV in simply 511.1 innings — and Clement anyplace supervisor John Schneider has performed him, it’s value noting the protection of Vladimir Guerrero Jr. After enjoying DH-caliber protection the previous two seasons (a mixed -16 FRV and -7 DRS), he’s been one run above common based on FRV (with all of his directional Outs Above Common measures transferring from adverse to optimistic) and 4 above common by way of DRS. That’s what you wish to see out of your franchise participant. About the one bitter be aware within the subject for the Blue Jays has been sounded by shortstop Bo Bichette (-5 DRS, -2 FRV).
Braves
Not a lot has gone proper for the Braves. Missing Ronald Acuña Jr. and Spencer Strider on the outset of the season, now with out Jurickson Profar and Chris Sale, and with a slew of different accidents (Reynaldo López and AJ Smith-Shawver) and a few underperformances (Ozzie Albies and Michael Harris II specifically) alongside the best way, they’ve by no means discovered a groove for very lengthy. But their protection has been wonderful.
Their catchers didn’t crack the highest three in any of the metrics, however veteran Sean Murphy and rookie Drake Baldwin are each above common throughout the board, and on fairly even footing relative to 1 one other. Matt Olson leads all first basemen in each DRS (12, one run shy of final yr’s majors-leading complete) and FRV (6). He’s performed each single inning for the staff at first base because the begin of the 2024 season — and proper now it’s paid off, as his offense has rebounded and he’s already matched final yr’s 2.6 WAR. Nick Allen, who supplanted Orlando Arcia at shortstop, is the place’s co-leader in FRV (10) and is second solely to Taylor Partitions in DRS (9); even with a 69 wRC+ up to now, he’s totaled 1.1 WAR. Harris is tied for fourth in DRS amongst middle fielders (9) and tied for fifth in FRV (7), however for as sturdy as these numbers are, his 50 wRC+ (!) has dragged his WAR beneath zero (-0.3). Spencer Schwellenbach is tied with former teammate Max Fried for the main league lead in DRS amongst pitchers (6).
Rangers
No staff has completed a greater job of changing batted balls into outs than the Rangers, whose .724 Defensive Effectivity leads the majors and is an enormous motive why the staff has allowed simply 3.48 runs per sport. A few of that owes to their ballpark; sure, it’s bizarre that after Globe Life Park was such a hitters’ haven, Globe Life Discipline has advanced right into a pitcher-friendly venue.
Per the superior metrics, the Rangers don’t have anyone who’s tremendously sturdy in each DRS and FRV. Adolis García’s 9 DRS is tied for second amongst proper fielders, however he’s common based on FRV. Shortstop Corey Seager (5 DRS, 1 FRV), left fielder Wyatt Langford (5 DRS, 0 FRV), and first baseman Jake Burger (3 DRS, 0 FRV) match that sample as effectively, all whereas lacking time as a result of accidents. Middle fielder Evan Carter leads the staff with 3 FRV (to go together with 3 DRS) in simply 237.2 innings within the subject, however each his bat and his well being lastly look like heading in the right direction. Second baseman Marcus Semien (1 DRS, 2 FRV) has been stable, and fortunately his bat confirmed indicators of life in June. Alas, the catching tandem of Jonah Heim and Kyle Higashioka has been in Substitute Degree Killers territory general, with Heim falling off from 5 DRS final yr to -5 this yr, even whereas he’s gone from -5 to 1 in FRV.
Yankees
The catching corps of Austin Wells and J.C. Escarra (with a spoonful of Ben Rice) leads the majors with 9.3 FRM, they usually’ve been sturdy in FRV if not DRS. Wells and proper fielder Aaron Choose are tied for the staff lead with 5 FRV; the latter is again at his pure place after enjoying simply eight video games there final yr, in comparison with 105 in middle. Cody Bellinger has been at his finest in his small pattern of proper subject video games, and has netted a modest 3 FRV (with 0 DRS) throughout the three outfield spots.
The infield has been considerably unsettled. Jazz Chisholm Jr. was above common at second base (3 DRS, 2 FRV in 251 innings), however has been beneath common since shifting to 3rd (-3 DRS, -2 FRV in 207 innings), although not less than the return of DJ LeMahieu (3 DRS, -1 FRV in 297 innings at second) has helped to offset the transfer. Even so, the Yankees have to improve one place or the opposite forward of the commerce deadline as a result of they’ve gotten sub-replacement-level offense from whichever place Chisholm isn’t enjoying. Shortstop Anthony Volpe’s enchancment on the plate has been offset by his defensive decline; he’s slipped from 10 FRV and 6 DRS final yr to 0 DRS and a pair of FRV this yr, and had a few key misplays in a one-run loss in opposition to the Blue Jays on Monday evening.
One different brilliant spot: Yankees pitchers have a significant league-leading 16 DRS, greater than double the full of the groups tied for second, the Mets and Royals (7 apiece). Past Fried, lefty specialist Tim Hill has 3 DRS in simply 36.2 innings, and 4 pitchers have 2 DRS, some whereas carrying even smaller workloads. The most important disappointment defensively has been rookie Jasson Domínguez, who has been wobbly in left (-5 FRV, -2 DRS) whereas additionally scuffling a bit on the plate.
Cubs
The stellar flychasing of Pete Crow-Armstrong is the most important motive why the Cubs make the reduce right here. His 12 FRV ranks second amongst all middle fielders, whereas his 11 DRS ranks third, however he’s not the one standout defender on the NL Central leaders. Nico Hoerner’s 11 DRS and 6 FRV each lead all second basemen.
Whereas no different Cub has greater than 1 FRV, the staff is especially sturdy in DRS. Along with the aforementioned gamers, left fielder Ian Happ and third baseman Matt Shaw each have 6 DRS, catcher Carson Kelly has 5 DRS, and shortstop Dansby Swanson, first baseman Michael Busch, and pitcher Colin Rea all have 3 DRS. As for that 1 FRV, every of the three catchers they’ve used (Kelly, Miguel Amaya, and Reese McGuire) has met that mark, primarily by means of their throwing, which offsets their barely subpar framing.
Tigers
The Tigers are the highest-ranked staff amongst people who didn’t wind up on the medal platform in any of the six classes. Their defensive star is beginning catcher Dillon Dingler, who has been distinctive in all the catching metrics into account; he’s tied for third in FRV (8), tied for fourth in DRS (6), and is seventh in FRM (3.5). Backup Jake Rogers is above common in all three classes as effectively.
Elsewhere, it’s robust to take Akil Baddoo‘s 4 DRS in left subject significantly given simply 32 innings (he’s presently in Triple-A), however no different Tiger is greater than three runs above common by both DRS or FRV. Zach McKinstry has netted 3 DRS and a pair of FRV whereas splitting time at second, brief, third, left and proper, and Javier Báez is at 2 DRS and a pair of FRV whereas enjoying middle subject (a brand new place), shortstop, and third. The latter’s offensive resurgence, together with Trey Sweeney’s struggles each within the subject (-5 DRS) and on the plate (68 wRC+), has led to Báez reclaiming the common shortstop job.
