Wow, you paid the price on a sell high sort of guy...Zambrano's been lights out, but that's a huge price to pay. Injury may be a concern with him, as his pitch counts have been high and he's shown signs of injury the last few times out, although it's not too serious at this moment. He's not the sort I trust as an ace, I don't know why, but that's just me. Has been consistent this year, but not so in the past. His WHIP was 1.32 and 1.45 the past two years...so I don't know.
I wouldn't deal either Berk or Guardado for him, personally...maybe Guardado only b/c of the trade possibility, actually.
