number of teams in league, stats used, keeper/non-keeper info would help...
I'd look for a good starting pitcher to drop Burrell for. I'd also look to improve at catcher, through a trade or free agency (though with your team size it looks like you're in a pretty deep league). Your outfield is deep; maybe try to trade one of your better ones (I'm not a big fan of Andruw Jones) for another SP. Good luck.
from cbs sportsline:
Home: 22-6 with a 3.00 ERA
Away: 9-15 with a 6.69 ERA.
So basically the Angels have a pitcher who throws like Roy Oswalt when he's near Disneyland, and Roy Disney when he's not.
