I'm all for giving him another shot... havent really called him out so far this year... waiting out the slump...
But if he has the attitude that he wants to quit... then retire. thats just fine. dont just go thru the motions like rios and collect a check.
I've also been asking for him to be on he field... LF or 1b for months now... let him start 5-10 games in the field straight and see how he does.
