Boston Red Sox vs. Athletics: July 29, 2026

Kalshi traders keep Boston favored on the road, in line with the club's turnaround since early July. Injury-wise, the Red Sox are without left-hander Garrett Crochet, on the 60-day injured list with a shoulder issue, and shortstop Trevor Story, also on the 60-day list with an abdominal injury. The Athletics are missing catcher Shea Langeliers, on the 60-day injured list with a torn meniscus, and designated hitter Brent Rooker, on the 60-day list with a knee injury, per Bleacher Nation.

Patrick Sandoval takes the mound for Boston, making his fourth start since returning from Tommy John surgery, with a 3.21 ERA in that stretch. Jacob Lopez starts for the Athletics at 1-5 with a 6.75 ERA, coming off five scoreless innings against the Twins in his last outing, per Bleacher Nation.

Boston is 18-3 in July on the strength of a 15-game winning streak earlier this month, though the Red Sox have batted just .231 with 10 home runs over their last 10 games. The Athletics have hit .265 with 12 home runs over the same stretch, per Bleacher Nation.
