One of Pittsburgh’s strengths this season has been its ability to limit opposing hitters. The Pirates enter this matchup holding opponents to just a .226 batting average, which is one of the better marks between these two teams. The concern lately has been offensive consistency after scoring only one combined run over the last two games against Philadelphia.
Cardinals Continue Winning at Night
St. Louis comes into this game with a 27-19 overall record and a 12-11 home record. The Cardinals have won three of their last five games and recently picked up victories over Kansas City and Oakland. St. Louis has played several close games during the recent stretch, including an extra-inning win over Kansas City and a one-run victory against Oakland.
The Cardinals are batting .241 as a team with 208 runs scored and 51 home runs. St. Louis owns a .321 on-base percentage and .388 slugging percentage while collecting 373 hits overall. On the mound, the Cardinals have posted a 4.12 ERA and 1.37 WHIP while allowing opponents to hit .252 against them.
One key advantage for St. Louis has been performance in night games, where the Cardinals hold an 18-7 record entering this matchup. The offense has also produced slightly more power than Pittsburgh with 51 home runs. However, the pitching staff has allowed more baserunners and a higher opponent batting average than the Pirates this season.
Pittsburgh Pirates vs St. Louis Cardinals Picks and Prediction
Pittsburgh Pirates vs St. Louis Cardinals Pick
- Pick: Pittsburgh Pirates Moneyline
Pittsburgh enters this matchup with the stronger pitching numbers overall, and Mitch Keller has been effective throughout the season with a 3.59 ERA and only three home runs allowed across more than 52 innings. The Pirates also hold advantages in batting average, on-base percentage, and opponent batting average allowed. While the recent losing streak is concerning, Pittsburgh still profiles as the slightly more balanced team entering this game. Against a St. Louis starter who has allowed nine home runs already this season, the Pirates have value in this matchup.
Pittsburgh Pirates vs St. Louis Cardinals Total Pick
- Pick: Under 8.5
I like the under in this game because Pittsburgh’s pitching staff has done a strong job limiting offense this season, especially with the .226 opponent batting average. Mitch Keller has also been effective at preventing home runs, which could help control the scoring pace early. St. Louis has played several close games recently, including 4-2, 5-4, and 2-0 results. With both teams entering after lower-scoring stretches and two offenses that have been inconsistent lately, this matchup feels favorable toward the under.
Final Score Prediction: Pittsburgh Pirates 4 – St. Louis Cardinals 3
