Even at his best, he walks batters:
Last season,
- one 1-hitter (2 BB)
- two 2-hitters (4 BB, 6 BB )
- two 3-hitters (4 BB, 4 BB)
Problem right now is, he's not at his best.
He's always had a tendency to blow up or hit a wall once in a while. His overall numbers have and will continue to speak for themselves. By mid season he'll be an all-star.
