I'd be careful starting him... he's the kind of guy who could ruin your ERA in any given start. He's still having trouble with walking people, and the K's aren't where they should be... but he's been getting results. June wasn't that good in terms of K/BB but he got some bounces (.212 BAA won't continue) and stranded runners, which led to an ERA below 4 finally. There are very few games of his where you look at his stat line and think "Wow, Zito had a really good game." Not someone I'd want on my team, and not somebody I'd try to buy low since he looks like he's going to revert to a 4.50 ERA with a WHIP and K/9 that will hurt more than they help.
