​Father time is undefeated, and when starting pitchers are entering their mid-30s, there's a good chance they lose some zip on their fastball. 


But when Arizona Diamondbacks ace Zack Greinke, who happens to be a $200-million pitcher, isn't reaching 90 mph on the radar gun, there should be a little concern.

“It’s still early,” Greinke said. “It is what it is. It’s still early and it’s not like some crazy, crazy thing. But it’s not ideal, either.”


It was obvious in his first year with Arizona that Greinke's stuff had taken a dip, but the shoulder issues toward the end of the season certainly didn't help. It's still early in camp, and with a veteran like Greinke, you don't expect him to max out in meaningless exhibition games.


But can we hit 90 on the gun, Zack?

“It doesn’t really concern me with Zack because I know he knows the process,” Diamondbacks manager Torey Lovullo said. “He’s building it backwards. He wants to get his foundation under him and kind of work it up that way.”


We shouldn't be concerned about the velocity just yet, but for his breaking stuff to be nasty come the regular season, Greinke needs a little more velocity to keep hitters off-balance.
