The Pittsburgh Pirates (57-74) head to Busch Stadium to face the St. Louis Cardinals (64-67) in an NL Central showdown Monday night. Despite their overall struggles this season, the Pirates enter with momentum after a weekend sweep of the Rockies behind ace Paul Skenes’ dominant performance. Meanwhile, the Cardinals are desperate to snap a concerning five-game home losing streak. I’ve zeroed in on Johan Oviedo’s return from injury creating an intriguing pitching matchup against Cardinals rookie Michael McGreevy, with several betting angles worth exploring.
Quick Picks:
- Best Bet: Pirates Moneyline (+121) ★★★★☆
- Top Prop: Johan Oviedo Over 4.5 Strikeouts (+125) ★★★☆☆
- Value Play: Under 8.5 Runs (-115) ★★★★☆
Pittsburgh Pirates vs St. Louis Cardinals Betting Odds & Latest Line Movement
| Market | Pittsburgh Pirates | St. Louis Cardinals |
|---|---|---|
| Moneyline | +121 | -144 |
| Run Line | +1.5 (-175) | -1.5 (150) |
| Total | Over 8.5 (-105) | Under 8.5 (-115) |
Opening Line: Cardinals -140, Total 8.5
Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers
The line movement has been minimal since opening, with the Cardinals shifting slightly from -140 to -144, indicating steady action on the home favorite. However, I’m noticing some interesting movement on the total, with the under juice increasing from -110 to -115. This subtle shift suggests professional bettors might be anticipating a lower-scoring affair than the market initially projected. With both teams featuring uncertain pitching situations and Busch Stadium historically playing as a pitcher-friendly venue (0.992 run factor), the smart money appears to be respecting the under despite both clubs’ recent defensive struggles.
Pitching Matchup: Johan Oviedo vs Michael McGreevy – Who Has the Edge?
Pittsburgh Pirates: Johan Oviedo (1-0, 4.50 ERA)
- Making just his second start of 2025 after recovering from Tommy John surgery
- Showed promise in his season debut with 6 IP, 3 ER, and 9 strikeouts
- Former Cardinal who may have extra motivation facing his old team
- Limited sample size (6 IP) but maintaining solid K/9 rate of 13.5
St. Louis Cardinals: Michael McGreevy (5-2, 4.26 ERA)
- Rookie right-hander who’s been surprisingly effective despite modest strikeout numbers (33 K in 57 IP)
- Outstanding control with just 7 walks all season (1.1 BB/9)
- Home/road splits favor his performance at Busch Stadium (3.82 ERA at home)
- Has struggled with consistency, allowing 4+ runs in three of his last five starts
Advantage: While McGreevy has more innings under his belt this season, I give a slight edge to Oviedo. His higher strikeout potential and the motivation of facing his former team create an intriguing matchup that could favor Pittsburgh despite Oviedo’s limited workload in 2025.
Bullpen Breakdown
The Pirates’ bullpen has been surprisingly effective lately, allowing just four runs across 13 innings during their weekend sweep of Colorado. Dennis Santana has emerged as a reliable closer with 9 saves and 13 holds, providing stability at the back end. Meanwhile, the Cardinals’ relief corps has been problematic during their current homestand, surrendering multiple late leads. JoJo Romero (4 saves, 18 holds) and Kyle Leahy (15 holds) have been bright spots, but inconsistency elsewhere has hurt St. Louis in high-leverage situations. With the Pirates’ bullpen better rested after Skenes’ seven-inning outing yesterday, Pittsburgh holds a slight advantage in late-game situations.
Key Betting Trends & Team Statistics That Matter
- Pirates lead the season series 5-4 against the Cardinals in 2025
- St. Louis has lost five consecutive home games, showing vulnerability at Busch Stadium
- Pittsburgh is 6-4 in their last 10 games while St. Louis is struggling at 3-7
- The Pirates’ offense has averaged 4.4 runs per game over their last 10 contests
- Cardinals are scoring just 3.8 runs per game in August, down from their season average of 4.37
- Pittsburgh is 18-44 on the road this season, one of the worst road records in MLB
- St. Louis is 35-30 at home, but their recent five-game home losing streak raises concerns
- The under is 7-3 in the last 10 meetings between these teams at Busch Stadium
Bryan Reynolds: The Offensive Catalyst Pittsburgh Needs
Bryan Reynolds has been Pittsburgh’s most consistent offensive threat and presents a significant challenge for McGreevy. Reynolds has been particularly effective on the road, hitting .271 with 12 homers away from PNC Park. His ability to drive the ball from both sides of the plate creates matchup problems throughout the game, and he’s had success against the Cardinals this season (.302 average with 3 HR in 9 games). McGreevy’s pitch-to-contact approach could play right into Reynolds’ strengths, especially since the Cardinals rookie has allowed a .262 batting average to switch-hitters this season. Look for Reynolds to be a key factor if Pittsburgh pulls off the road upset.
Busch Stadium Factor: How the Venue Influences Today’s Game
Busch Stadium ranks as the 16th most hitter-friendly park in MLB this season with a runs factor of 0.992, making it slightly pitcher-favored. The park is particularly suppressive for home runs (0.917 factor), which benefits both starting pitchers today. Evening temperatures around 75°F with minimal wind should create neutral conditions, further emphasizing pitching and defense. The Cardinals’ recent defensive struggles at home (11 errors in their last 8 games) could be a deciding factor in a park where run-scoring opportunities are typically at a premium. With both offenses ranking in the bottom third of MLB in runs scored, Busch Stadium’s dimensions should help keep this game relatively low-scoring.
Expert Prediction & Best Bets for Pirates-Cardinals Showdown
Primary Play: Pittsburgh Pirates Moneyline (+121)
I’m seeing tremendous value on the Pirates as road underdogs here. The Cardinals’ five-game home losing streak coupled with Pittsburgh’s 5-4 edge in the season series makes the +121 price attractive. Oviedo brings extra motivation facing his former team, and the Pirates’ bullpen is better rested and performing more consistently. St. Louis has shown vulnerability as a favorite, going just 2-7 in their last 9 games when laying -140 or more. While Pittsburgh’s road record is concerning, their momentum from sweeping Colorado should carry over against a struggling Cardinals squad.
Strong Value Play: Under 8.5 Runs (-115)
Busch Stadium’s pitcher-friendly confines combined with both teams’ offensive inconsistency points toward the under. McGreevy’s control (just 7 walks in 57 innings) limits free baserunners, while Oviedo showed strikeout potential in his season debut. The last 7 meetings between these teams at Busch Stadium have averaged just 7.3 total runs, and I don’t see either offense breaking out tonight. With both bullpens performing better than their season averages lately, I’m confident in the under hitting at 8.5 runs.
Worth Considering: Bryan Reynolds Over 1.5 Total Bases (-135)
Reynolds has been Pittsburgh’s most reliable hitter, especially on the road where he’s slugging .476. He’s recorded multiple total bases in 6 of his last 8 games and has historically performed well at Busch Stadium (.286 career average). McGreevy’s pitch-to-contact approach creates opportunities for Reynolds to drive the ball, particularly if the rookie leaves pitches over the plate. While the juice at -135 isn’t ideal, Reynolds’ consistency makes this a solid secondary play.
Player Props Worth Targeting in Today’s Matchup
| Player | Prop | Odds | Rating |
|---|---|---|---|
| Johan Oviedo | Over 4.5 Strikeouts | +125 | ★★★☆☆ |
| Bryan Reynolds | Over 1.5 Total Bases | -135 | ★★★★☆ |
| Michael McGreevy | Under 4.5 Strikeouts | -170 | ★★★☆☆ |

Final Thoughts: Pirates’ Momentum Trumps Cardinals’ Home Field Advantage
This matchup presents a classic case where the betting line doesn’t fully account for recent team performance and momentum. While the Cardinals have the better overall record and home-field advantage, their current five-game home losing streak reveals significant vulnerabilities. Pittsburgh enters with confidence after sweeping Colorado and has already proven they can handle St. Louis this season, leading the season series 5-4. Oviedo’s return creates an intriguing pitching matchup that could neutralize the Cardinals’ offensive threats, especially in a pitcher-friendly Busch Stadium. When combining all factors, the Pirates at +121 represent one of Monday’s best values on the MLB slate.
Score Prediction: Pirates 4, Cardinals 2
