Yes, you did detect sarcasm. I would have been happier if he wasn't going to be ready for the start of the season for three reasons:
1. It would have avoided any controversy regarding who makes the rotation. Wakefield is not going to be happy going to the pen. If you think he has no ego, you are kidding yourself. He thinks he has earned the spot, and he will not be happy going to the pen. Buchholz will definitely not be happy if he is the 6th starter. He's hoping to step up to prime time this season.
2. In April, with the days off, you barely need 5 starters never mind 6 starters. The 6th starter will not get a spot start for a couple of months-- probably June. That's not going to sit well with the #6 starter.
3. In the last several seasons, Wakefield has had a tendency to break down in August. He still has an unrepaired tear in his labrum for about 3 years. If he was ready in late June, he might stay healthy down the stretch run when we need him most.
It's time to let Buchholz take the reins so Wakefield will be the odd man out, but he will not be happy about this. He's going on record about that already and they haven't even reported to camp.
