Jered Weaver's No-Hitter

Click image to enlarge

Jered Weaver threw 121 pitches in his no-hit performance against the Minnesota Twins last night, striking out nine and walking one.

Weaver's heat maps show that he kept the ball away from Twins' lefties all night. He threw a mix of fastballs, curveballs, changeups, and sliders.

Of the 121 pitches that Weaver threw, only 49 actually located within the strike zone. This isn't surprising as Weaver's zone% is fairly low (45.8% since the start of 2011, bottom 12% of the league). What is interesting is the number of strikes that home plate umpire Mark Carlson denied Weaver.  Weaver threw 21 pitches within the strike zone that were not swung at by Twins hitters; only 12 of those pitches were correctly called strikes.  Take a look at the correct call heat map:

However, you will also notice the large incorrect section outside to lefties. Weaver was actually getting a fairly wide strike zone. Of the 47 pitches Weaver threw out of the strike zone that were not swung at, 12 were called strikes.  Two of those strike calls were strike three calls, both to lefties.  However, neither of the two were outside pitches.  The first came in the 7th to Alexi Casilla - the small blue dot on top of the strike zone.  The second was the strike out of Denard Span in the 9th - that inside blue dot.

All in all, Weaver lost nine strikes in the strike zone and gained twelve strikes outside of the strike zone. Given the results, he's probably not complaining.

Jered Weaver Head Hunting

Jered Weaver of the Los Angeles Angels of Anaheim received a six game suspension on Tuesday for throwing at Alex Avila of the Detroit Tigers.  Note that Weaver is not afraid to pitch inside to left-handed batters.

MLB, RHP inside to LHB, 2011.Weaver tends to come farther inside than most righties, and up and down a bit more.  His high pitches usually end up over the plate, not near the batter's head.

Look where he threw the pitch to Avila:

Weaver's Devastating Fastball

Jered Weaver of the Los Angeles Angels of Anaheim and starting pitcher for the American League All-Stars owns the most devastating fastball in the majors this season.  In plate appearances ending on a Weaver fastball, he recorded the lowest weight on-base average (wOBA) of any pitcher (min 200 PA on fastballs):

Weaver manages to keep his fastball away from both lefties and righties.  The following graph shows his pitch loationa and movement against left-handed batters:

Jered Weaver, fastball vs. LHB, 2011. Location on the left, movement on the right.Note the great movement toward the left-handed batter.  Weaver can start this pitch outside, and the break brings it back over the outside corner.  Even when he misses, batters sometimes go after the pitch, resulting in a swing and miss.  His wOBA against lefties on his fastball is .224.

Against right-handed batters, he works the other side of the plate.

Location on the left, movement on the right.Note that Weaver gets even more lateral movement with his fastball against right-handed batters.  He starts the ball inside, and then it breaks over the outside part of the plate.  Batters see a pitch they can pull, but it ends up a pitch they should be driving the other way.  Instead of getting good wood on the ball batters get weak ground balls or flies bunched in the middle of the outfield.  That helps him to a .226 wOBA against righties.
