Randy Johnson threw 52 pitches in batting practice against Diamondbacks prospects Saturday and wants to pitch in an exhibition game this month.

It was the first time he's thrown BP since back surgery in October. "I'm pleased with where I'm at right now, as I have been with every step," Johnson said. "To not have any real setbacks other than maybe a stiff back here and there, I think that's to be expected, especially with the workload I've been doing this quickly. I'm pretty pleased."
