10/09 Guardians vs White Sox

Guardians starting pitcher: Parker Messick White Sox starting pitcher: Hagen Smith

Game 4 of this best-of-five series is at Chicago's Guaranteed Rate Field. The White Sox won the first two games in Cleveland - 3-0 on October 4 and 4-3 on October 6 - before Cleveland won Game 3 by a 9-3 score yesterday, so Chicago leads the series 2-1 and Cleveland faces elimination. The two teams finished the regular season nearly even (Cleveland 85-77, Chicago 84-78), and the White Sox hold a 9-7 edge in this season's meetings.

Messick has a 2.60 ERA over 190.2 innings with a 3.12 FIP and 3.06 xFIP - results a bit better than the work, but the work itself is very good. He misses bats (19.3% K-BB%, 11.2% swinging-strike rate). His last five starts have been fine (3.03 FIP over 23.2 innings), though a .348 BABIP means he has been hit a lot, and his outings have gotten shorter (4.1, 3.0 and 5.0 innings). His velocity in Game 1 was the highest of the stretch (95.7 mph average, 97.9 max). On the road he has a 2.22 ERA over 93.1 innings, but a 3.59 FIP and 88.9% strand rate suggest some luck. He has pitched well against the White Sox (3.00 ERA, 2.90 xFIP and 35 strikeouts over 30 innings in five starts), though he allowed five homers, and he took the loss in Game 1 after giving up two earned runs in 4.1 innings.

Smith has a 1.31 ERA and 2.59 FIP over 34.1 innings. He's very hard to hit (14.5% swinging-strike rate, .121 opponent average) but walks a lot of batters (15.3% walk rate). His last five appearances ran from 0.2 to three innings, and he pitched yesterday in Game 3 as well (0.2 innings, two walks, one earned run), so expect a short start followed by a parade of relievers. He sits at 94.7-95.2 mph. Against Cleveland he has a 3.00 ERA over nine innings, but with 11 walks (a 26.8% walk rate) his command issues have been even more pronounced.

Neither lineup is confirmed, so these numbers use each team's previous lineup. Cleveland (100.6 wRC+) has warmed slightly to a .337 wOBA over the last five games (vs .320) and scored nine runs yesterday. Brayan Rocchio (.495, two homers), Patrick Bailey (.438, two homers) and Jo Adell (.454) are hot, while Jose Ramirez is cold at .272 and Angel Martinez is hitless over five games. Cleveland's numbers against Smith are all one to four at-bats, too small to mean much.

The White Sox (113.2 wRC+) have cooled to a .292 wOBA over the last five (vs .332). Munetaka Murakami (36 HR) is slumping at .246 but is 3-for-6 against Messick, and Randal Grichuk is 5-for-14 (.357) against him. Chase Meidroth is hot at .422, while Tommy Pham has struggled badly all season (26.4 wRC+).

The bullpens have been similar over the last 10 games (2.89 ERA for Cleveland, 3.02 for Chicago), but the White Sox pen has worked more recently (22 innings across 11 arms vs 17 across eight), and with another bullpen-heavy game likely today, that workload keeps piling up. It will be chilly - 14.4°C with winds of 2.4 m/s and a 2% chance of rain - but nothing that should change the game.

In summary, Messick, with 190 innings under his belt, gives Cleveland the heavier starting option, while Chicago will likely ride a short, walk-prone outing from Smith into its bullpen. The keys are how deep Messick, whose recent starts have gotten shorter, can carry a Cleveland team facing elimination, and whether a heavily used White Sox bullpen can contain a Cleveland lineup that just put up nine runs.
