Parnell’s Final Tally Last Night

57 (possibly 58) fastballs, 10 sliders.

In terms of pitch movement, here’s what Parnell looked like last night:

The clump in the top left are the fastballs (ranging in velocity from 88 to 98 MPH.  If some of those 88MPH pitches are changeups, that’s a pretty fast changeup and it may be confusing Pitch F/X, which called one of those pitches a changeup and one a “two seam fastball.”   Nonetheless Parnell threw 58 fast pitches with the same type of break on them.

In the bottom right of the plot are his 10 sliders which averaged 85MPH.

That makes it 84% fastballs on the night, higher than his fastball rate (79.4%) when pitching out of the bullpen this season.

Again, as we learned two posts ago on this blog, this is not a typical formula for success for a Major League starting pitcher.

And finally, here’s where his pitches landed relative to the strike zone:

Looks to me like only 2 of Parnell’s 10 sliders were in the strike zone (although batters swung at two of the sliders that were out of the zone). 

Unfortunately, last night’s performance only reinforces that this guy is an unfinished product who has made little progress with his pitches over the (now) full season he’s spent in the Major Leagues.  Maybe the Mets want this guy to figure things out himself at the Major League level, but they’d probably serve him better by providing him some coaching and let him work on his secondary pitches at AAA.
