Seattle Mariners vs Philadelphia Phillies Prediction and Picks, August 26, 2026

For this game, we want to see more than 7 runs scored between the Seattle Mariners and the Philadelphia Phillies. The Phillies are on a hot streak, winning 9 out of their last 10 games and scoring about 1.6 runs more than their opponents on average lately. They've also been hitting well against left-handed pitchers, even matching the league's typical performance against them. The Mariners have won 6 of their last 10 games, but they struggle against lefties, which could mean some scoring opportunities for the Phillies. Playing at home helps Seattle, but their overall performance against left-handers shows they might not be as strong here. So, while we have a good chance for runs, remember that both teams could keep things close tonight.

Seattle Mariners vs Philadelphia Phillies: Philadelphia Phillies -1.5 Spread (+146)

The Philadelphia Phillies are on a hot streak, winning 9 of their last 10 games and scoring 1.6 runs more than their opponents lately. They are hitting well against left-handed pitchers, matching the league's average, which is a good sign against Seattle's struggling lefties. This matchup at T-Mobile Park gives them a chance to keep that winning momentum going. The Seattle Mariners have won 6 of their last 10, but they have faced challenges against left-handed starters this year. With the teams this closely matched, the Phillies at -1.5 could be a smart pick. The biggest risk is that Seattle tends to perform better at home, so this game could be tighter than expected.
