San Francisco Giants vs Cincinnati Reds Prediction, Odds and Picks for Today, 04/15/26

The Reds took the first game of this series against the Giants 2-1 on Tuesday night, but Wednesday’s matchup could be a bit more high scoring. The pitching matchup in this one pits San Francisco’s Tyler Mahle against Cincinnati’s Rhett Lowder. Mahle is set to face his former team for the first time and will be making his first start at Great American Ball Park as a visitor. The Cincinnati ballpark has given him issues in the past, as the 31-year-old right-hander owns a 5.02 ERA and 1.402 WHIP in 55 career games at GABP. The Reds possess a well-rounded lineup that should be able to give Mahle some issues in his return to Cincinnati.

On the other side, Lowder is set to make just his 10th big league start in this contest. He has endured an up-and-down start to the 2026 campaign and is coming off a tough outing against the Marlins in which he allowed 8 hits and 5 runs over 5.1 innings of work. Lowder is still learning his way around a big league mound, so he could be susceptible to some struggles. Make it a small play, but look to the over in this one.
