What would the Red Sox postseason bullpen look like?

With 46 video games to play within the common season, the Crimson Sox are actually a shocking 4 full video games away from the Texas Rangers and Cleveland Guardians (the primary groups out of the playoffs) and have an 75.1% chance of constructing the playoffs, per Fangraphs. Whereas the paths to enjoying time are clearer inside the lineup and the rotation, the bullpen feels prefer it has fairly a little bit of variance with regards to who may be included on a playoff roster.

Let’s check out the 16 potential candidates that I may conceivably see pitching within the postseason, breaking them out into 5 tiers:

Notice: I’m together with Shutdowns vs. Meltdowns as “SD” and “MD” within the statline. Fangraphs’ explanation is here.

Aroldis Chapman: 49 G, 44.2 IP, 3-2, 21/23 SV, 1.21 ERA, 0.76 WHIP, 31.0% Ok-BB, 29 SD, 5 MD

After a 15.4 BB% from 2021-2024, Chapman has reduce that precisely in half to 7.7% over 44 ?
? innings with the Crimson Sox as their capital-C Nearer. Completely masterful in any and all conditions. Chapman is within the top-2 percentile in xERA, xBA, Fastball Velo, Whiff%, and Ok%. Arguably, one of many three most vital gamers that should keep wholesome for this crew to reach the postseason.

Garrett Whitlock: 43 G, 52.2 IP, 5-1, 2.91 ERA, 1.12 WHIP, 21.3% Ok-BB, 21 SD, 6 MD

The trusted eighth-inning man, Whitlock seems like 2021 Garrett Whitlock once more. He has solely allowed a run in three of his previous 28 appearances, whereas 34 of his 43 appearances total have come within the seventh inning or later. After a 23% Ok-rate over the previous two seasons, Whitlock is placing batters away with a 30.6 Ok%, which is within the 92nd percentile in baseball.

Justin Wilson: 43 G, 35 IP, 3-1, 2.83 ERA, 1.37 WHIP, 18.2% Ok-BB, 17 SD, 9 MD

After a shaky first ten appearances as a Crimson Sox, Wilson has allowed simply seven complete runs in his previous 33 appearances. Whereas it doesn’t at all times happen within the seventh inning or later, Wilson is often introduced in for the largest spot within the sport {that a} key left-handed hitter, or stretch of hitters, must be shut down. His Whiff% and Onerous-Hit% sit within the ninetieth percentile.

Tier 2 – Deserving of a Spot (if wholesome…)

Greg Weissert: 52 G, 48 IP, 4-3, 2.81 ERA, 1.17 WHIP, 10.1% Ok-BB, 20 SD, 7 MD

You could possibly argue that Weissert deserves to be within the Excessive Leverage tier on the entire, however since July 1, he’s been deployed within the sixth inning in half of his outings, and his Ok% is within the twenty first percentile. Weissert was overused in June, showing in 15 of the crew’s 26 video games and understandably hit a little bit of a wall late in that month. However he hasn’t given up an earned run in his previous 10 appearances and deserves to be again within the Circle of Belief. His 52 appearances are tied for fith within the American League, and solely two behind the league chief, Louie Varland.

Justin Slaten (IL-60): 24 G, 23.1 IP, 1-4, 3 SV, 3.47 ERA, 10.0% Ok-BB, 15 SD, 5 MD

Slaten has been coping with a nerve difficulty in his shoulder, which is printed here, however has been throwing off a mound this week and hopes to be again by the top of August. Slaten was the very best leverage “non-Chapman reliever” by way of the top of Could with 18 of his 24 appearances coming within the eighth inning or later, tallying three saves within the first month of the season. He may simply rejoin the highest group with a powerful September, however will first must show that he’s wholesome in an August rehab.

If the 5 guys above are all in good type, it’s tough to see any of them not on the roster. If we assume {that a} rotation shortens to 4 within the playoffs, then we would wish to seek out 4 extra relievers from the next (lengthy) record for a complete of 9. Since rosters broaden to twenty-eight gamers in September, the crew would possible carry 9 relievers in that month, as effectively.

Tier 3 – One thing to Show

Brennan Bernardino: 47 G, 43.2 IP, 4-2, 3.09 ERA, 1.26 WHIP, 7.3% Ok-BB, 6 SD, 7 MD

Would have been in Tier 2 every week in the past, however his current demotion and a 22:36 BB:Ok ratio this season go away simply sufficient doubt. Bernardino has not pitched since his final MLB outing on July 28 and really effectively may simply be getting a “reset” on an arm that has made 49 appearances (two of which have been within the minors) already this season. Bernardino has extra meltdowns than shutdown appearances this season, with solely 19% of his pitches thrown this season being in high-leverage conditions however hitters are batting simply .199 towards him this season (with a .225 xBA). Bernardino additionally has an 81st percentile GB%.

Chris Murphy: 12 G, 20 IP, 2-0, 2.25 ERA, 0.80 WHIP, 16.0% Ok-BB, 3 SD, 0 MD

Bernardino’s demotion could have partially been as a result of effectiveness of Murphy in current weeks. Except for the three residence runs he allowed at Wrigley Subject in mop-up responsibility, Murphy has been lights out, with 9 of his 12 outings being scoreless. He has been requested to get 5+ outs in seven outings and is gaining belief as a protracted man within the Sox pen.

Steven Matz (STL + BOS): 34 G (2 GS), 57 IP, 5-2, 3.44 ERA, 1.18 WHIP, 16.2% Ok-BB, 8 SD, 9 MD

Sticking with the lefties theme, Matz has thrown two shutout innings since arriving in Boston. He was wonderful for the Cardinals over the primary six weeks, however since Could 14th, has a 5.04 ERA (3.84 FIP) and a 1.42 WHIP.

Jordan Hicks (SF + BOS): 25 G (9 GS), 59 IP, 1-7, 2 SV, 6.41, 1.59 WHIP, 9.3% Ok-BB, 1 SD, 6 MD

Hicks has a 6.10 ERA in 10 ?
? IP with Boston up to now, and has 8 BB+HBPs to go along with 8 strikeouts. He’s gotten two saves and regarded nice in these outings, however his struggles have in any other case been an extension of the pitcher that he was in San Francisco. Hicks is in simply 12 months two of a 4 12 months, $44M contract, and was possible simply regarded as a method to transfer wage again to Boston in return for what they have been taking over with Rafael Devers.

Cooper Criswell: 7 G (1 GS), 17.2 IP, 1-0, 3.57 ERA, 1.58 WHIP, 5.0% Ok-BB, 1 SD, 0 MD

Criswell is a depth arm for each the rotation and as a protracted man out of the bullpen. With a 4.48 profession ERA in 154 ?
? innings, he’ll possible throw some extra innings that matter within the 2025 common season. May simply be a thirteenth arm in a playoff sequence, ought to a sport go to further innings or a starter is pressured to exit early.

Kelly was a key piece to the bullpen a 12 months in the past and has only in the near past returned to Worcester from the 15-day IL with an indirect harm. With Boston, Kelly has thrown 22 ?
? IP with a 5.56 ERA (3.64 FIP). If Kelly can discover his stuff and throw strikes, it could actually’t be dominated out that he’s again up with the membership in September.

He was recalled on Tuesday when Jorge Alcala was DFA’d. Campbell has seven saves and a 4.17 ERA in 45 ?
? IP (34 G) at Worcester and seems like he’ll solely be in Boston quickly.

A six-year MLB veteran, Burdi has nice numbers at Worcester when wholesome this season. Over 23 innings, his ERA is 1.96 with 11.7 Ok/9. He just lately returned from foot and hip accidents at Worcester, however did throw 5 ?
? IP for the massive membership in Could of this season with out permitting a run.

Guerrero just lately shifted to the 60-day IL with an elbow sprain. Though he hasn’t been dominated out for the season, there is no such thing as a information of throwing but, and he can’t be relied upon to be obtainable in October.

By no means has the discharge of a pitcher with a 3.31 ERA in 19 appearances ever been extra comprehensible. Final Tuesday, Alcala allowed two runs in ?
? of an inning, forcing the utilization of Aroldis Chapman for a one-out save. On Saturday, Alcala allowed two of the three baserunners he confronted to succeed in base, forcing the utilization of Aroldis Chapman for a two-out save. This previous Monday, Alcala allowed three runs, together with two residence runs, in ?
? of an inning, forcing the utilization of their three highest leverage relievers in an pointless 8-5 last. Unnecessarily put on down the nearer 3 times in a single week? He gone.

Tier 5 – Prospect Name-Ups

Payton Tolle (MiLB mixed numbers): 17 G (15 GS), 4-1, 2.93 ERA, 76.2 IP, 1.02 WHIP, 31.1% Ok-BB

The 22-year-old Tolle made 11 dominant appearances at Excessive-A to begin the season, adopted by six appearances at Double-A that have been extra dominant than the Excessive-A begins, earlier than being promoted to Worcester this week. He has thrown 76 ?
? innings on the season and it’s not inconceivable to suppose that if the crew needs to handle his workload in a couple of weeks, perhaps they shouldn’t waste these bullets within the minor leagues. Tolle, the #1 prospect on Sox Prospects, would should be added to the 40-man roster earlier than September 1 to be eligible for postseason play. Even when that occurred, he would nonetheless be eligible for Rookie of the 12 months incentives in 2026 since he would fall in need of the 50-inning and 45-roster day thresholds.

David Sandlin (MiLB mixed numbers): 19 G (14 GS), 88.2 IP, 7-4, 3.65 ERA, 1.18 WHIP, 17.9% Ok-BB

Copy and paste the Tolle paragraph from above, solely barely much less dominant. Sandlin is the #9 prospect at Sox Prospects.
