St. Louis Cardinals: Michael McGreevy (6-2, 4.17 ERA)
- Showing excellent command with just 11 walks in 69.0 innings

Advantage: Cardinals. McGreevy has shown better command and results in a larger sample size. His ability to limit walks should be particularly valuable against a Giants lineup that can be patient at the plate.
Bullpen Breakdown
Both bullpens have had their challenges this season, but San Francisco maintains a slight edge in overall effectiveness. The Giants’ bullpen ranks 6th in MLB with a 3.79 ERA, led by closer Ryan Walker (14 saves) and setup man Randy Rodriguez (4 saves, 13 holds). The Cardinals’ relief corps sits in the middle of the pack with JoJo Romero (7 saves, 20 holds) anchoring the late innings along with Kyle Leahy (17 holds). With both rookie starters likely on pitch counts, bullpen performance could ultimately decide this contest.

Rafael Devers: The Catalyst Powering Giants’ Playoff Push
After a somewhat disappointing start to his Giants tenure, Rafael Devers has exploded in recent weeks, becoming the driving force behind San Francisco’s resurgence. Over the last 10 games, Devers is hitting .395 with 5 homers, providing the middle-of-the-order thump that was missing for much of the season. His hot streak has coincided perfectly with the Giants’ 9-1 run, demonstrating how his performance directly impacts the team’s success. If McGreevy makes a mistake tonight, Devers has shown he’s locked in and ready to capitalize.
Busch Stadium Factor: How the Venue Influences Today’s Game
Busch Stadium ranks as one of the more neutral MLB venues, sitting just below average with a 0.992 runs factor and 0.917 home run factor. The spacious outfield tends to suppress power while allowing for extra-base hits into the gaps, which could benefit contact hitters on both sides. Evening conditions in St. Louis are expected to be pleasant with minimal wind, providing little atmospheric advantage to either pitchers or hitters. One factor to note is that Cardinals hitters are naturally more comfortable with the dimensions and sight lines, which contributes to their stronger home performance (39-33).
Expert Prediction & Best Bets for Giants-Cardinals Showdown
Primary Play: San Francisco Giants Moneyline (-104)
The Giants’ recent form is simply too strong to ignore at essentially even money. While McGreevy holds a slight edge over Seymour on the mound, San Francisco’s offense has been scorching hot, averaging over 7 runs per game during their recent surge. The momentum is clearly on their side, and I see value in backing a team that’s playing with supreme confidence against a Cardinals squad that’s been treading water. At -104, you’re getting the hotter team at a discount.
Strong Value Play: Under 8.0 Runs (-105)
While the Giants have been scoring at will lately, I see this as a potential lower-scoring affair. Busch Stadium plays slightly below average for run production, and both starting pitchers, despite their inexperience, have shown the ability to limit damage. The Cardinals’ offense has been inconsistent, and I expect the Giants’ bullpen to perform well in the later innings. With value on the under at -105, this represents a solid contrarian play against the public perception of San Francisco’s hot offense.
Worth Considering: Lars Nootbaar Over 1.5 Hits+Runs+RBIs (-150)
Nootbaar has been one of the few bright spots in the Cardinals’ lineup lately, hitting .282 over his last 10 games. He should continue his productive stretch against Seymour, who has struggled with left-handed hitters. While the juice is heavy at -150, Nootbaar’s consistent production at the top of the order gives him multiple paths to clearing this modest total.
Player Props Worth Targeting in Today’s Matchup
| Player | Prop | Odds | Rating |
|---|---|---|---|
| Lars Nootbaar | Over 1.5 H+R+RBI | -150 | ★★★☆☆ |
| Rafael Devers | Over 1.5 H+R+RBI | -130 | ★★★★☆ |
| Heliot Ramos | Over 1.5 H+R+RBI | -125 | ★★★☆☆ |
| Masyn Winn | Over 1.5 H+R+RBI | -105 | ★★★☆☆ |
| Patrick Bailey | Over 0.5 H+R+RBI | -180 | ★★★★☆ |
Final Thoughts: Giants’ Momentum Trumps Cardinals’ Home-Field Advantage
When handicapping September baseball, current form often carries more weight than season-long statistics. The Giants have completely transformed over the past two weeks, with their offense firing on all cylinders and their pitching staff doing just enough to support their run production. While the Cardinals have the slight pitching advantage and home-field edge, I can’t ignore San Francisco’s momentum and the value presented at nearly even money. Look for the Giants to continue their playoff push with a hard-fought victory at Busch Stadium.
Score Prediction: San Francisco Giants 4, St. Louis Cardinals 3
