"He's got a plus fastball and then when he throws his changeup, obviously it makes his fastball look that much better," Runge said. "But the thing that was impressive tonight was that he had plus command of his breaking ball and he had plus control of his curveball. That may have been the best curveball we've seen him throw in his young career. When you see pitchers develop like that, you know they've got a chance to move really fast."
Naturally, Ben Badler, the Baseball America prospect guy who saw Teheran pitch, saw him pitch the best game of his short pro career. He apparently had every pitch working perfectly, and was completely fooling hitters -- he struck out 11 in 8 innings. Runge was also quoted as saying how much Teheran has matured as a pitcher.
Per the last line of the quote above, it will be interesting to see how fast the Braves move Teheran. They've been cautious with him so far, but he's still really young, so there's plenty of time.
