Pitching Matchup

Seattle Mariners - Logan Gilbert

Gilbert is 11-7 with a 3.36 ERA and 1.02 WHIP across 155.1 innings. The right-hander has recorded 162 strikeouts while allowing 120 hits and 39 walks. Gilbert has surrendered 21 home runs, but his low WHIP shows how well he has limited overall baserunners. His 162 strikeouts lead the two scheduled starters, and his 155.1 innings provide Seattle with a proven workload for Sunday’s series finale.

Toronto Blue Jays - Max Scherzer

Scherzer is 1-7 with a 7.02 ERA and 1.54 WHIP through 50 innings. The right-hander has allowed 52 hits, 25 walks and 12 home runs while recording 36 strikeouts. Scherzer’s 77 combined hits and walks have created frequent baserunners, while his 12 home runs allowed represent more than one every five innings. His ERA is 3.66 runs higher than Gilbert’s, and Scherzer has worked 105.1 fewer innings this season.

Seattle Mariners vs Toronto Blue Jays Game Pick

  • Seattle Mariners

Sunday’s starting matchup favors Seattle because Gilbert has posted a 3.36 ERA and 1.02 WHIP across 155.1 innings. Scherzer owns a 7.02 ERA and 1.54 WHIP through 50 innings, creating a clear statistical gap between the starters. Toronto has the stronger batting average, but Seattle has hit 27 more home runs this season. The Mariners also rank 13th in MLB pitching, two places behind Toronto. With Gilbert recording 162 strikeouts and limiting baserunners, Seattle is the pick despite its poor road record this season.

Seattle Mariners vs Toronto Blue Jays Over/Under Pick

  • Over

Recent scoring patterns make the Over the stronger direction for Sunday’s series finale. Toronto scored eight runs against Seattle on Friday and has produced at least three runs in four of its last five games. Scherzer’s 7.02 ERA, 1.54 WHIP and 12 home runs allowed across only 50 innings are likely to create runs. Seattle has struggled recently at the plate, but the Mariners have 156 home runs this season. Toronto has also allowed 595 runs, while Seattle has surrendered 591 through Friday’s game. The over is the play.
