At the end of the season, it's probably pretty safe to offer Bell arbitration. If he accepts, the Brewers can use him or trade him.
Who would want a 33 year old with a bad back and a lifetime OPS slightly above .700?
I would offer him the door, but never arb.. he's a fill in for all those injuries, if Melvin offers him Arb I'll be shocked.
He'll be set free the day after the season.
