Breaking down Tim Lincecum's Changeup

It goes without saying that Tim Lincecum has one of the best changeups in the game.  Since 2008, batters have only made contact on 55.5 percent of their swings, good for 4th best in the league among pitchers throwing at least 500 changeups.  Lincecum has also induced a high swing rate of 59.0 percent over that period, good for 5th best in the league.  The combination of the two speaks volumes to the quality of his change, as Lincecum has been able to successfully fool batters with the pitch, getting them to both swing and miss frequently.

As can be expected with any changeup, the more downward movement you get on the pitch, the harder it is to hit.  Lincecum's change has averaged 15.8 feet per second of downward velocity when crossing the plate since the beginning of the 2008 season, but when put in play, the ball averaged an entire foot less of vertical movement.

Here's a breakdown of his changeup by vertical movement (PVZ):

It's quite telling based on contact rate alone how much more effective the change is when it has more downward velocity. It's important to note that a changeup with less vertical movement will more often end up higher in the zone, as those with more movement often end up down in the zone. So you're bound to get less contact with changeups that end up scuffing the plate than those that float over the strike zone. But as his expected K-Rate indicates (as well as his overall swing percentage), Lincecum is getting batters to swing at those changeups down in the zone, resulting in a lot of strikeouts.

The plummeting xwOBA that accompanies the increase in downward velocity on Lincecum's change is impressive. With 15 feet per second of movement or more, batters essentially can do nothing with his change. The expected walk rate jumps a bit with more than 17 ft/s of movement, and that is mainly due to the number of those changeups that fall out of the strike zone for balls. However, the actual walk rate on those changeups is around 7.0%, which is still lower than the 8.2% walk rate Lincecum holds on all pitches since 2008.

Huff vs. Hunter

Last night, Aubrey Huff deposited a first pitch cutter from Tommy Hunter into the right field seats for a two-run HR.  It was all the offense the Giants would need to win the game.  In the regular season, Huff was one of the best cut fastball hitters in the league.

Top 2010 NL Batters vs. the Cutter by wOBA (min. 50 PA)Aubrey Huff In Play SLG% vs. Cutters since 2008As noted during the broadcast last night, Hunter had to endure a nine pitch at bat from Freddy Sanchez just prior to Huff's third inning AB.

Freddy Sanchez's 3rd Inning ABMuch was made of how Huff was able to get a good look at Hunter's stuff with Sanchez fouling off pitch after pitch ahead of him.  But as you can see, Hunter pitched Sanchez fairly carefully. That AB probably did more to tire out Hunter and disrupt his rhythm.  After finally retiring Sanchez on a ground out, he then grooved the very next pitch right over the heart of the plate.  Huff did not miss it.

Cain's Mark on the Postseason

Matt Cain has been brilliant so far this Postseason.  He's held batters to a .173/.259/.187 line over 21.1 innings.  He's allowed 13 total hits, only one for extra bases, and has struck out 13.

When he broke into the league, Matt Cain showcased a mid-nineties fastball.  He's turned into more of a finesse pitcher, with his fastball now averaging around 92 mph.  As a result, Cain no longer blows away batters with high cheese as much as he once did, but instead relies on his secondary pitches more.

During the regular season, Cain tended to get hit harder up in the zone.  Against lefties, pitches down and in were hit hard as well.
