I used to watch Volquez pitch a lot back in Cali when he was with the Padres. He's a solid mid rotation arm. But they used him as an ace atleast one season. His main downside is he can be erratic. He's good for a couple of walks a game, sometimes more. But he also brings above average strikeouts. In our current rotation, he'd probably be our strikeout leader. That's assuming Buch gives you less than 130 ip. E-rod might challenge him.
