With most deliveries accompanied by his customary grunts, Zack Greinke threw four fastballs at 91 mph in the first inning on Monday morning. He hit 90 mph three times in the second.
But the Diamondbacks’ ace did not throw a fastball that exceeded 89 mph after that, and later he refused to answer questions about his velocity, despite having thrown well, giving up just two hits in five innings against minor-leaguers in an instrasquad game at Salt River Fields.
“I don’t know,” Greinke said. “I mean, the first time, it’s an interesting story. I’m not going to answer velocity questions every time the whole season. I mean, you’ve got to pick and choose your times you ask me about that.”
