Escobar said he would spend the next few days "doing exercises, keep throwing, pitch in a game again to see how my hand responds and go on from there. It could have been worse. He checked my shoulder, my elbow, my neck, and everything was fine. He thinks it's a nerve that's not firing."
Escobar worked to six batters against the Cubs on Sunday and said he struggled to grip the baseball from the start. He exited with two outs and the bases loaded after two walks and a hit batsman.
The 36-year-old is a non-roster invitee in Brewers camp who has been limited to one Major League appearance since 2007 because of shoulder injuries. He is trying to win a job in Milwaukee's bullpen.
