The Yankees pitcher is aiming to return to the mound.

Stroman received a cortisone shot in his left knee to reduce swelling.
“The MRI was good, but he had some swelling in there somewhere,” Yankees manager Aaron Boone said Sunday. “So try to eliminate that, hopefully get him ramped up pretty quick and, hopefully, something that really helps him move it forward.”
Boone was unclear on how Stroman injured his knee in the first place.
“I’m not even sure,” Boone said. “Even watching the video, watching how [he was] not finishing properly on his front leg and I think that was due to the knee.”
The Yankees will hope to see Stroman return to the mound as soon as possible as their pitching options diminish.
Yankees’ Ben Rice thriving in lead-off spot

The New York Yankees were unsure who would fill their lead-off hitter role, but designated hitter Ben Rice has shown to be a solid candidate early in the season.
Through 13 games played and 42 at-bats so far this season, Rice is batting .310 with four home runs and five RBIs. His performance has impressed manager Aaron Boone.
