Giants vs Cardinals Key Matchups and Game Preview
San Francisco Leans on Roupp
Right-hander Landen Roupp takes the mound for the Giants carrying a 9-13 record with a 4.00 ERA and 1.28 WHIP across 150.2 innings. Roupp has allowed 121 hits with 139 strikeouts, 72 walks and just 11 home runs, giving him a solid ability to limit damage despite some ongoing command issues. His workload also dwarfs what St. Louis will counter with on Monday.
Cardinals Counter With Mathews
St. Louis responds with left-hander Quinn Mathews, who enters just 1-3 with a 4.11 ERA and 1.50 WHIP through only 30.2 innings. Mathews has allowed 32 hits and 14 walks while striking out 28, and that limited sample combined with an elevated WHIP suggests San Francisco should have opportunities to create traffic if the lineup stays patient.

Giants Power From Devers
Rafael Devers leads San Francisco's offense with 37 home runs and 98 RBI while batting .258, and Jung Hoo Lee owns the team's best average at .276 with a .318 OBP and .400 slugging percentage. The Giants hold a .407 to .385 advantage over St. Louis in team slugging percentage and have hit 172 home runs compared with the Cardinals' 157.

SF and STL Betting Trends
- San Francisco already swept the first three games of the season series against St. Louis, with each win coming by three runs or fewer.
- The Giants have dropped their last three games.
- The Cardinals have lost two of their last three games.
- Public moneyline money has been mixed, with STL backing as high as 90% on some dates and SF backing as high as 66% on others.

Key Injuries and Things To Know for SF and STL
San Francisco Giants injuries: The Giants are missing Willy Adames and Marcelo Mayer, while Victor Bericoto is also on the injured list.
St. Louis Cardinals injuries: St. Louis is without Everson Pereira and Blaze Jordan, while Jose Fermin is day-to-day.
Giants vs Cardinals Side and Over/Under Picks
With Roupp owning the stronger WHIP and a far larger workload than Mathews, San Francisco has enough of a starting-pitching edge to stay competitive again after already sweeping the first three meetings between these two clubs. The combination of a shaky Mathews outing and two offenses capable of scoring also points toward value on the Over.
- Side Pick: Giants moneyline (+119)
- Total Pick: Over 7.5
Final Score Prediction
Given Roupp's larger workload and steadier command compared to Mathews, along with San Francisco's success in the season series so far, this projects as another close game the Giants can find a way to win.
- Final Score Prediction: San Francisco 5, St. Louis 4
