The Yankees sent embattled lefthanded reliever Chasen Shreve to the disabled list with an AC joint sprain in his pitching shoulder. Shreve, who gave up a pair of two-run homers in the seventh inning Wednesday night, has allowed seven home runs in his last 13 2⁄3 innings. He underwent an MRI and received a cortisone injection, and the Yankees said he will not pick up a baseball for at least seven days.

“He said he’d been dealing with it a couple days and today it was really sore,” Joe Girardi said, adding that “it could” be responsible for Shreve’s struggles, which include a 5.21 ERA. He underwent tests Thursday. The Yankees called up lefty Richard Bleier from Triple-A Scranton/Wilkes-Barre.
