Red Sox vs. Blue Jays Prediction: Sonny Gray Aims for Win No. 15 in Rogers Centre Opener

Sonny Gray is chasing win No. 15 against a Toronto lineup that just lost its ace to season-ending surgery, and that mismatch is the whole story of this series opener.

Quick take:

• Pick: Boston Red Sox moneyline
• Why: Sonny Gray’s 2.78 ERA against a Blue Jays offense in freefall, with Jameson Taillon making just his second big-league start of the year on the other side
• The number to watch: Gray is 14-2 with his team going 14-6 ATS in his starts this season

Boston rolls into Rogers Centre at 64-53, six games back in a stacked AL East but still very much alive for a Wild Card spot after ripping off eight wins in nine games. Toronto, meanwhile, is scuffling at 56-63, sitting fifth in the division and staring up at a Red Sox club that’s outscored opponents by 85 runs on the season. The Blue Jays did just take two of three from the Phillies over the weekend, but this is a fundamentally different animal than a middling NL club — Boston’s lineup has been a wrecking ball for two weeks straight.

Why the Market Isn’t Buying Toronto at Home

Boston opened as a -164 favorite and books have it hovering around -160, with Toronto sitting anywhere from +138 to +163 depending on the shop — check the MLB odds board for the latest lines before first pitch. The run total sits at 8.5, reflecting a Blue Jays pitching staff that’s been stretched thin and a Red Sox offense that’s been unloading on everybody in sight. Sharp money likes Gray here — Boston is 14-6 against the spread in his 21 starts, a number that tells you the market has learned to respect this rotation slot all year.

Recent Form

The gap between these two clubs’ trajectories over the last two weeks is about as stark as it gets in a midweek series.

Gray’s Ace Season Meets a Blue Jays Staff in Crisis

Gray has been the best pitcher in the AL East all summer, sitting at 14-2 with a 2.78 ERA, a 1.15 WHIP, and 106 strikeouts over 119.2 innings. He’s given Boston length and results start after start, and there’s nothing in Toronto’s lineup construction that screams matchup nightmare for him — the Blue Jays rank 19th in team average and 30th in home runs as a club. Taillon, on the other hand, is making just his second start back in the majors this year and has been rocked for a 5.96 ERA, allowing four strikeouts in four innings his last time out. That’s about as clean a starting pitching mismatch as this series will produce.

Toronto’s lineup isn’t fully healthy either. Vladimir Guerrero Jr. is back from a hamstring issue and hit a home run in his return over the weekend, but he’s been dealing with back and hamstring problems most of the summer and is running a .261 average with a .698 OPS that’s well off his career norms. George Springer has missed time with a tight shoulder, Trey Yesavage is out for the season with a knee injury, and Luis Urías just went down with a quad strain. Ernie Clement (.285) and Nathan Lukes (.268) have carried water offensively, but this isn’t a lineup built to hang with a Red Sox club that just scored 14, 4, 12, and 13 runs across a four-game stretch against Chicago and Oakland.

Boston has won nine of its last ten games, batting .288 as a team with 16 home runs over that stretch.

That kind of offensive surge, paired with a true frontline starter on the mound, is a tough combination for a banged-up club playing out the string in fifth place. Wilyer Abreu, Willson Contreras, and Ceddanne Rafaela have all been hot contributors in the middle of Boston’s order, and even with Rafael Devers’ departure reshaping the lineup earlier this year, this group has found its rhythm at exactly the right time to make a Wild Card push. Toronto’s pitching depth simply isn’t equipped to slow it down over a four-game set that opens with their weakest link on the mound.

Boston also just took two of three in a wild series with the White Sox that saw both bullpens get taxed, but manager Alex Cora has had extra rest built in before this series, and Gray profiles as exactly the arm to stop any bleeding if the bats cool off even slightly.

Prediction and Best Bet

Gray’s track record against a shorthanded Toronto lineup, plus Boston’s red-hot offense catching a struggling second-year arm in Taillon, points to a comfortable Red Sox win to open this series.

The pick:

1. Prediction: Red Sox 6, Blue Jays 2
2. Best Bet: Red Sox on the moneyline

With this much separation in both starting pitching and recent form, laying the moneyline price is more appealing than needing Boston to also cover -1.5 against a Toronto team still capable of a bullpen-game rally.
