In a final act of desperation, the Los Angeles Angels elected on Friday to deactivate underperforming center fielder Vernon Wells from their 25-man roster and then immediately reactivate him to see if that would fix the problem. 'Vernon hasn't been running so smoothly lately, and he keeps freezing all the time, so we're deactivating and reactivating him a couple times because sometimes that works,' said Angels general manager Jerry Dipoto, who confirmed that he instructed trainers to blow on Wells a few times while he was deactivated to remove any built-up dust. 'We already tried putting some other guys into the same slot, and they worked fine, so we're pretty sure the roster's not fried. I guess we could try jiggling him, too.' At press time, Wells was preparing for tonight's game against the Detroit Tigers by repeatedly removing his helmet and putting it back on again.
