David Price threw a 50-pitch simulated game on Thursday, using all four of his pitches.

The Boston Red Sox were pleased by Price's velocity. His fastball hovered around 93-95 mph.

Price threw his first simulated game on Tuesday.

"In the very beginning we really wanted to put a feel on it because, and I think the world of him, but David has that tendency as he's building to not build," Dave Dombrowski said. "Wants to go from zero to 100. And I thought that having John [Farrell] involved and our staff involved would be much better off to have. Not that he would not listen to anybody, but when John says 'Hey back off a but little here' or Carl [Willis] or our training staff, they know him much better in that regard."
