Boston enters the game looking to maintain its strong road form, holding a 30-22 record away from home this season.

On the mound, Boston sends left-handed pitcher Jake Bennett (6-W, 2.74 ERA) against Athletics left-hander Gage Jump (4.00 ERA, 68 Ks). Boston's lineup relies heavily on Ceddanne Rafaela (109 hits) and catcher Willson Contreras (22 HR, 66 RBI). Meanwhile, the Athletics showcase young power hitter Tyler Soderstrom (17 HR, 50 RBI) as they attempt to defend their home field.
