Alexander (shoulder) threw approximately 20 pitches in the bullpen before Friday's game against the Rangers and looked good, the Associated Press reports.
The veteran southpaw was throwing to manager Mark Kotsay, who served as a stand-in for a left-handed hitter and therefore had a first-hand look at how Alexander performed. Kotsay said after the session that he and the training staff would evaluate Alexander's recovery from the activity over the weekend to determine the left-hander's next steps. Given his experience and the fact he's a reliever, Alexander could conceivably return from the injured list without the need for a rehab assignment.
