It is Olsen's second consecutive season where he has been hurt, not pitching as much or as well as he expects, and now he is in the pen and questioning if he even has a job next year. I'd imagine he's disappointed with how the team as done as well. Not terribly surprising he doesn't look happy.
To some extent I'd even extend the same excuse to Morgan.
I'm starting to side with Morgan. The whole damn world is on his case. Other players get to decide if they play winter ball, Nyjer should get to choose too. He spent last season rehabbing, and I know that's no picnic. If people let him cool off , I think he will settle down.
