Player Prop to Watch
Julio Rodríguez (Mariners) – Total Bases: 1.5
Rodríguez has been heating up at the plate, batting .326 over the past 10 games. Look for him to make an impact against Wheeler, especially with a depleted Phillies bullpen.
Alec Bohm (Phillies) – RBI Total: 0.5
Bohm has been clutch hitting with runners in scoring position, making him a strong candidate to collect at least one RBI tonight.
Prediction & Best Bets
Spread: Phillies -1.5 → Given Wheeler on the bump and their solid home form, Philadelphia has the edge to cover this line.
Total: Under 8.5 → With two elite pitchers on the mound, expect a low-scoring affair dominated by zeros.
Player Prop: Julio Rodríguez Over 1.5 Total Bases → He’s simply locked in, and this line offers good value.
The Mariners will fight hard, but missing key players like JP Crawford and going up against one of the NL’s premier arms may be too much on the road. The Phillies sneak out a close win behind Zack Wheeler’s brilliance and a late-inning RBI from Alec Bohm.
Final Score Prediction: Phillies 4, Mariners 2
