As the Yankees gear up for a pivotal three-game series against the Athletics, manager Aaron Boone is still undecided on his Sunday starter. The options are Marcus Stroman and Allan Winans, both of whom were set to throw side sessions on Friday. Stroman, struggling with a 6.97 ERA in his rehab starts after knee inflammation, faces pressure after his latest outing, where he allowed five earned runs in 3.2 innings. Winans, who debuted in the majors with a 0.90 ERA in Triple-A, allowed four runs over 4.1 innings in his first start but has shown promise.

The Yankees will be without J.C. Escarra due to paternity leave, and Boone indicated they might not make any roster moves, as Escarra is expected back Sunday. Additionally, utility player Braden Shewmake and outfielder Everson Pereira are also unavailable, adding to their challenges as they face left-handed pitcher JP Sears. Boone confirmed that Jonathan Loáisiga is still recovering from an illness, which could further limit the bullpen options.
