The Boston Red Sox (64-53) visit the Toronto Blue Jays (56-63) at Rogers Centre on Monday at 7:07 p.m. ET, with Kalshi's head-to-head market pricing Boston at 60% and Toronto at 40%, as of this writing.
Boston sits third in the AL East but holds the third American League Wild Card spot, part of a run that has carried the Red Sox from a season-worst mark under .500 in June to a playoff position. Toronto sits last in the division and has already dealt away veterans Daulton Varsho and Kevin Gausman since the trade deadline, according to the Boston Globe.

Boston Red Sox vs. Toronto Blue Jays: August 10, 2026
Kalshi's number leans heavily on the pitching mismatch. Sonny Gray takes the ball for Boston with a 14-2 record and 2.78 ERA, while Toronto counters with Jameson Taillon, making just his second start since arriving from the Chicago Cubs at the trade deadline, per NBC Sports. The gap between an established ace and a pitcher still finding his footing on a new roster is doing most of the work in Monday's price.
Boston's most consequential absence remains left-hander Garrett Crochet, who recently began a throwing program while working back from left shoulder inflammation, and newly acquired catcher Adley Rutschman has yet to make his Red Sox debut while nursing left wrist inflammation, according to the Boston Globe. For Toronto, outfielder George Springer is day-to-day with a shoulder issue, per ESPN.
Gray has struck out 106 batters across 21 starts and carries a 1.15 WHIP, numbers that put him among the American League's ERA leaders, per ESPN. Taillon's 5.96 ERA in his brief Toronto tenure is a steep drop from the pitcher he was for most of his career with Pittsburgh and Chicago.
Boston has won eight of its last 10 games and carries a five-game road winning streak into this series, outscoring opponents by 35 runs over that stretch, according to Spectrum News. Toronto has gone 6-4 over the same span, with a .228 team batting average that ranks near the bottom of the majors.
Boston's Wild Card Push
Kalshi's Postseason Qualifiers market has Boston at 88% to reach the playoffs. The Red Sox hold the third AL Wild Card spot, with Detroit sitting 1.0 games back of the cutoff and Minnesota and Cleveland each 1.5 back, according to sportsbrackets.net. That gap leaves real room for the field to tighten before October.
Boston's World Series Odds
Kalshi's Pro Baseball Champion market prices Boston at 7.9% to win it all, fourth-highest in baseball and ahead of NL East leader Atlanta. The Red Sox are one of just three American League teams priced above 15% to win the pennant since the end of June, a byproduct of a 29-7 stretch built on a pitching staff that ranks third in the AL in ERA, per SI.
Kalshi markets now predict:
Boston takes a 60% market edge and one of the AL's tightest Wild Card margins into Monday's series opener at Rogers Centre.
