Yankees manager Girardi has put Joba Chamberlain on notice: Shape up or his primary setup role will be taken by fast-improving right-hander David Robertson.
Chamberlain has posted an 8.71 ERA since mid-May. In his last outing before the All-Star break, the big right-hander allowed four runs to Seattle. Robertson, meanwhile, has posted a 2.52 ERA over his past 23 appearances after a slow start.
"I’m not saying on a daily basis I am going to change our eighth-inning guy, but you have to earn your roles here," Girardi told the New York Daily News. "And we evaluate on a daily basis."
