Steven Matz's fastball not as fast as expected

I never expected that the starting Mets pitcher with the slowest average fastball velocity this season would be Steven Matz, his four-seamer taking even longer to reach the catcher's mitt than Bartolo Colon's or that Matt Harvey, with his health issues, would have the third fastest average velocity.

On the other hand, the fact that Harvey lasted the fewest innings per start (IP/GS) among the main "starting five" could have been a red flag that something was wrong.

Average velocity of #StevenMatz's fastball (vFA) less than #BartoloColon's, lowest of #Mets starters. Unexpected. pic.twitter.com/h2oLWGUqxS
