Lackey will be a strong number three IF he is healthy. Right now I'm trying to convince myself what he felt was an adhesion. Wasn't he touching 95? The guy was airing it out. If he's hurt or can't stay healthy it's a major blow.
I'm sold on Tazawa as a starter. Long relief is a waste of his talent. The idea is to use him in games where the team is down big early?
If there are medical concerns then no, but he is way younger and much further removed from his elbow surgery than Lackey.
Doubront I'm not sold on. He's not a kid anymore. He's shown he can pitch really well, but he needs to make a move this year. He was better last year than his ERA showed. I'm willing to toss out his bad patch, because he recovered, and pitched well. The conditioning issues concern me. If he was a bit out of shape and pitching great I wouldn't care, but he isn't pitching great, and even if his conditioning is not a factor the club wants him in shape. The fact he shows up a bit out of shape for a second time after the heat he got the last time worries me.
