What's at stake
Boston enters at 53-49 and 24-6 in its last 30 games, a run that included a 15-game winning streak. A win today would give the Red Sox their sixth straight series victory and keep their AL Wild Card push rolling. The Blue Jays sit at 47-57, last in the AL East, with the postseason all but out of reach.
Friday's win belonged to Romy Gonzalez, who broke an eighth-inning tie with an RBI double, and Aroldis Chapman, who struck out two in the ninth for his 24th save. Toronto got a three-RBI night from Kazuma Okamoto but couldn't hold a lead late.
Pitching matchup: Gray vs. Cease
Sonny Gray takes the ball for Boston carrying a 12-1 record and a 2.48 ERA, numbers that have him squarely in the AL Cy Young conversation. The 36-year-old is in the midst of one of the best seasons of his career, posting a 1.07 ERA across his last four starts and completing a quality start in nine straight outings. Gray is 4-4 with a 2.99 ERA in 16 career appearances against Toronto.
Dylan Cease counters for the Blue Jays at 6-5 with a 2.67 ERA, and his case for the AL Cy Young is just as legitimate. Cease started the All-Star Game for the American League this season and leads the AL in strikeouts with 155, averaging 13.55 per nine innings. His last outing was a rough one, surrendering five runs in six innings against Tampa Bay after two dominant scoreless efforts.
The AL East division race
The AL East race sits above both clubs tonight. Traders give the Yankees and Rays a 44% chance each to win the division, with Boston sitting at 12% despite their recent hot streak and Toronto priced at just 1%. For the Red Sox, the Wild Card is the realistic path. For the Blue Jays, tonight is about pride and a Cy Young audition.
The bigger picture: World Series odds
Neither club features prominently in the World Series market. The Dodgers lead at 34%, with the Yankees second at 14% and the Brewers at 10%. The Red Sox check in at 6%, modest but alive, while the Blue Jays do not register among the top contenders.
