When did he "quit"?
He quit when he pinched hit against the Yankees and took three staight pitches down the middle.
He quit when he turned a blooper just beyond the infield into a triple by flopping around on the ground..............................and then laughing about it. All while his team was getting spanked by the Angels.
He quit by missing three crucial games because of a "knee injury" when his team desperately needed his bat. (Notice how he's running down the first base line now?)
He quit by not running out a sure infield hit down the third base line while his team was being no-hit in the 8th inning.
