New York Yankees pitcher Domingo Germán has voluntarily entered inpatient treatment for alcohol abuse, the team announced Wednesday. Germán, who threw a perfect game June 28 at Oakland, was placed on the restricted list two days before his 31st birthday. Germán is 5-7 with a 4.56 ERA in 20 appearances this season. He was scratched from his scheduled start Monday night against Tampa Bay, with the Yankees saying it was because of armpit discomfort. The right-hander then entered in relief and tossed five scoreless innings of two-hit ball.
