Per MASN...
Showalter doesn't necessarily view Joseph as the favorite to back up Wieters and the other candidates must beat him out for the job.
"I hadn't really thought about it that way," Showalter said. "We've got a lot of guys to pick from for the most part that stay in the mix, whether they make it or not. I like that flexibility. But the familiarity we have with the job that Caleb did last year certainly works for him, but that doesn't mean it favors him and I don't think he expects that.
So, Caleb's performance last year helps him... but, while Buck will say it helps him, he'll also say it doesn't really help him...
Just keeping everybody on their toes... if Caleb's not on the team, I'll eat my hat.... (not my O's hat, but another hat...)
