Scouting report from Major League Umpires' Performance, 2007-2010, by Andy Goldblatt:

His plate numbers support the argument that R/9 tends to follow strike zone size. They also support the argument that Iassogna is inconsistent. ... Iassogna's career ejection rate stands at three percent, well above average.

Scouting report from an angry message board commenter:

That is a lazy ass umpire who gave up on the curveball, wanted to raise his hand, but figured "nah - too late to call it correctly now. If I call it now, later than I usually call it, it will show everyone that I know I missed that pitch. Anyways, the kid is dealing, he will get this pitch back. It won't matter."

A lazy ass fucking umpire who blew the call and cost a remarkable performance because of his own lazy incompetence, giving up on a pitch. Fucking twat. This guy Iassogna has been a bad lazy umpire for as long as I can remember. He holds grudges longer than he holds his strike zone.

Fuck him.

Average K/9 (2011): 14.4

Average BB/9 (2011): 6.1

Sample PITCHf/x strike zone: April 24, 2012. If Iassogna has historically been inconsistent, then this recent graph from a Johan Santana-Josh Johnson matchup shows that his zone will be quite liberal in 2012.
