Halladay Versus Beltre

Adrian Beltre (TEX) is one batter of many Roy Halladay (PHI) shut down over his career.  The two meet Friday night as the Rangers visit the Phillies.  In his career, Roy held Beltre to a .185/.214/.296 slash line in 28 plate appearances.  Adrian doesn't strike out much against Roy, just five times in his career, but he doesn't get much out of putting the ball in play.

PITCHf/x covers the last eleven battles between the two (2008-2010) and shows us why Roy shuts down Adrian.  First, look at Adrian's hot zones:

Roy Halladay vs. Adrian Beltre, pitch frequency, 2008-2010.That's a total of 36 pitches.  Notice how nicely Roy fills that green bubble on the inside part of the plate, putting pitches between Adrian's hot zones inside.  Halladay avoids large swaths of the plate altogether, but sometimes tempts Beltre outside.

One big help for Roy appears to be reputation.  Beltre was never known as a selective hitter, and Halladay puts pitches where he wants, so Roy seems to get the calls on taken pitches:

Halladay and Left-Handed Batter Home Runs

Roy Halladay (PHI) allowed his second home run of the season on Sunday, a shot by Dan Uggla (ATL) that cost him the game.  Halladay is a great pitcher, but he does allow a decent number of home runs. Having given up just two one quarter of the way through the season is unusual for him.  The other unusual aspect of this season is that both home runs came off the bats of right-handed batters.

During the three previous seasons, Halladay saw a left-handed batter about 55% of the time, and they hit 38 of the 64 home runs against him, or 59%.  Roy worked lefties in and out, avoiding the middle of the plate as much as possible:

Roy Halladay, pitch frequency against LHB, 2011.Roy throws mostly on the outer half of the plate against left-handed batters now, and he's been rewarded with no home runs allowed from that side of the plate.  Lefties slugged .372 against him from 2008-2010, but that's down to .277 this season.

Roy Halladay's Change Up

Roy Halladay (PHI) struck out 14 Padres on Sunday, April 24, 2011, tying a career high.  He tied San Diego in knots due to his change up.  The Padres had no problem recognizing his fastball.  They swung when the pitch was in the strike zone:

Roy Halladay, taken fastballs, April 24, 2011.Roy's change up came in ten miles an hour slower than his fastball.  It showed the same horizontal movement, but dipped more.  The Padres got that pitch backwards:

Roy Halladay, taken change ups, April 24, 2011.I suspect that once a batter takes one of those change ups in the heart of the strike zone, he's more likely to swing at one down further.  Halladay is a master at messing up a batter's timing, changing speeds and locations.  This allows him to work efficiently, going deep in games.  All those skills were on display Sunday.
