Toronto Blue Jays vs Seattle Mariners Prediction and Picks, August 29, 2026

The Seattle Mariners have struggled against left-handed pitchers this season, and the Toronto Blue Jays have a solid chance to exploit that at home. Toronto has had a bit of a rough patch, winning only 4 of their last 10 games, but they play better at Rogers Centre, where they've had a more balanced home record compared to their away games. The Blue Jays are rated as a strong favorite here, especially with the Mariners also having trouble against lefties. The biggest risk is that both teams have shown inconsistency, and the Mariners have won 6 of their last 10 games. Still, the Blue Jays have the advantage of home field and a chance to take control of this matchup.
