Chasing a Halladay Changeup

Roy Halladay of the Philadelphia Phillies starts Tuesday's All-Star game for the National League.  There is no pitcher in 2011 better at getting batters to swing out of the zone at a change up:


Pitcher Team Change Ups Chas%
Roy Halladay PHI 339 0.573
Felix Hernandez SEA 482 0.486
Carl Pavano MIN 370 0.481
James Shields TB 572 0.479
Kyle Lohse STL 337 0.468
Chris Capuano NYM 451 0.459
Anibal Sanchez FLA 335 0.452
Justin Verlander DET 415 0.447
Ricky Romero TOR 370 0.444
Dillon Gee NYM 384 0.441
Shaun Marcum MIL 582 0.435
Cole Hamels PHI 430 0.434
Roy Oswalt PHI 229 0.429
Max Scherzer DET 381 0.426
Bronson Arroyo CIN 228 0.416


Roy puts a large gap between himself and #2 Felix Hernandez.  Halladay achieves this by getting more sink on his change up than most right-handed pitchers:
