Pitching Matchup

San Francisco Giants – Landen Roupp

Roupp is 7-12 with a 4.31 ERA and 1.30 WHIP across 129.1 innings. The right-hander has allowed 108 hits, 60 walks, and 10 home runs while striking out 128. Roupp faces a Cleveland lineup batting .233 with a .313 on-base percentage and .370 slugging percentage. The Guardians lack strong season-long power numbers, but Roupp’s 60 walks could provide Cleveland opportunities to score without depending heavily on extra-base hits.

Cleveland Guardians – Gavin Williams

Williams is 11-7 with a 3.74 ERA and 1.08 WHIP through 149 innings. The right-hander has allowed 116 hits, 45 walks and 24 home runs while recording 190 strikeouts. Williams faces a San Francisco lineup batting .248 with a .306 on-base percentage and .407 slugging percentage. His strikeout total and low WHIP give Cleveland an advantage against a Giants offense that has scored two runs or fewer in three of its last five games.

San Francisco Giants vs Cleveland Guardians Game Pick

• Cleveland Guardians

Cleveland is the game pick behind the stronger starting pitcher, better staff numbers, and San Francisco’s poor road record. Williams enters 11-7 with a 3.74 ERA, 1.08 WHIP and 190 strikeouts, while Roupp carries a 4.31 ERA and has issued 60 walks. The Guardians also own a 3.82 team ERA compared with San Francisco’s 4.38 mark. Cleveland won Tuesday’s opener 8-1, and the Giants have lost four of five while posting a 22-41 road record this season overall.

San Francisco Giants vs Cleveland Guardians Over/Under Pick

• Under

The under is the total pick because both offenses have lacked consistent scoring despite Cleveland’s eight-run performance Tuesday. San Francisco has scored two runs or fewer in three of its last five games, while Cleveland has been shut out twice during the same five-game stretch. Williams brings a 3.74 ERA and 1.08 WHIP into the matchup, strengthening Cleveland’s chances of limiting the Giants again. Roupp has allowed only 10 home runs in 129.1 innings, helping San Francisco limit Cleveland’s power.
