Perfect Game, PITCHf/x style

By Tangotiger, 05:25 PM

ESPN notes:

Halladay got 26 called strikes in this game and struck out six batters looking. Using Pitch F/X technology, a technology set up in conjunction with MLB, we had Doug Kern of ESPN Stats & Information look at whether those strikes were really strikes.

Of the 26 called strikes, seven were, via Pitch F/X standards, out of the strike zone, or close enough that they would be “borderline strikes.”

There was a pattern:

Six of these called strikes were off the plate to the left side (looking in from the pitcher’s view). But more notably:

Of Halladay’s six strikeouts, five came on pitches that were not in the Pitch F/X strike zone.

* Strikeout pitch to Chris Coghlan in the first inning was inside.

* 2-1 pitch to Josh Johnson in the third was low.

* Strikeout pitch to Hanley Ramirez in the fourth was outside.

* First pitch to Johnson in the sixth was inside.

* Strikeout pitch to Coghlan in the seventh was inside.

* Strikeout pitch to Ramirez in the seventh was outside.

* Strikeout pitch to Wes Helms in the ninth was outside.

Eric Polsky gets into it as well, using Brooks Baseball.

Ideally, the comparisons would be made against Halladay’s strike zone, and the Mike DiMuro’s strike zone.
