The Nationals’ revolving-door bullpen spun around again Friday when the club placed Aaron Barrett on the 15-day disabled list with a strained biceps muscle and officially added fellow right-hander David Carpenter to the major-league roster.
Barrett’s injury, which forced him from Thursday night’s game in Milwaukee during the bottom of the eighth inning, was diagnosed Friday as a biceps strain. The full severity of the ailment (and a timetable for his return) wasn’t immediately known, but it does appear the young right-hander avoided a more serious injury to his elbow or shoulder.
Barrett departed Thursday’s game after giving up the eventual winning run on an opposite-field single to Brewers second baseman Scooter Gennett, then after throwing two straight balls to Hernan Perez.
