Sonny Gray is confirmed for Boston, and his season line has been excellent at 12-1 with a 2.48 ERA, 1.12 WHIP, and 90 strikeouts over 101.2 innings. He has also been dominant recently, posting a 1.59 ERA over his last seven outings. That combination of current form and season-long run suppression makes him the more trustworthy starter in this game. Jameson Taillon is confirmed for Toronto, and his 2026 line is less stable at 2-5 with a 5.38 ERA, 1.32 WHIP, and 65 strikeouts across 72 innings. He has the track record of a veteran, but the current season numbers show more baserunners and more damage allowed than Gray. That creates a clearer early edge for Boston, especially if Taillon does not command the zone and give Toronto a clean start.
Boston is the stronger side overall, with better offense, better run prevention, and better recent form. A lower-scoring game fits the statistical picture, but the Red Sox have the more reliable starter and the deeper relief group, so the lean is Boston by a small margin in a game that stays under the number, with a projected score of Red Sox 5, Blue Jays 3.
Boston enters with an 8-2 mark over its last 10, while Toronto is 6-4 over the same stretch. The Red Sox have also built a much stronger season run differential at +84 compared with Toronto's -59, and Boston's staff has paired that with a 3.50 team ERA and a 2.92 bullpen ERA.
