Orioles vs Cardinals Key Matchups and Game Preview
Trevor Rogers is the confirmed starter for Baltimore and brings a 9-8 record, 4.14 ERA and 1.24 WHIP into the matchup over 132.2 innings, with 114 strikeouts against 36 walks. St. Louis had not announced its starter as of Thursday morning, which adds uncertainty to the pitching matchup and makes Baltimore's established starter an important advantage. Rogers has been more stable than Baltimore's overall pitching numbers, as the Orioles own a 4.19 team ERA and 1.34 WHIP. St. Louis is similar statistically with a 4.24 ERA and 1.34 WHIP, so there is not much separating these clubs on the mound over the full season.
Baltimore's Offense
Baltimore is batting only .237 as a team, but the Orioles have produced 163 home runs and 604 runs while posting a .399 slugging percentage. Pete Alonso has been the centerpiece of that attack, hitting .276 with 32 homers, 91 RBI, a .365 OBP and .516 slugging percentage. Baltimore's offense has scored 21 runs across the first two games of this series alone.

St. Louis's Offense
St. Louis has hit .241 as a team with 139 homers and 593 runs. Alec Burleson is batting .291 with 21 home runs and 98 RBI, while Jordan Walker leads the club with 27 homers and has driven in 97, giving the Cardinals real pop in the middle of their order despite the series deficit.
Orioles Bullpen and Injury Notes
Baltimore recently lost Tyler O'Neill to the 10-day IL with a right shoulder issue, while Ryan Mountcastle remains on the 60-day IL, reducing the Orioles' available power and depth. Relievers Felix Bautista and Ryan Helsley are also sidelined, which can make protecting late leads more difficult for Baltimore.
Cardinals Pitching Uncertainty
St. Louis is without shortstop Masyn Winn because of a left thumb fracture and outfielder Everson Pereira with a hand contusion, while starting pitchers Andre Pallante and Hunter Dobbins are also on the IL. Those pitching injuries help explain why the Cardinals are still undecided on a starter and could force them to lean heavily on their bullpen in this finale.
