標題[情報] Halladay’s New Changeup
時間Thu Aug 12 19:34:15 2010
Roy Halladay開季前和投手教練學到了曲球以外的第二個out-pitch -- 以叉指的握法
投變速球, 結果練出了第四個有效球路, 以前的握法變速球使用率僅有5%, 但變更了握法
後雖然變速球的球速與先前差不多, 但掉得幅度比以前銳利的得多, 目前使用率為12%,
每100球是+1.5 run, 加入這個新的變速球後, 讓對手今年的揮空率, 滾地球率, 長打率都
比前3年要好看。雖然球探一般認為他不需要練出第四個球路, 但他還是練出來了。這樣可
以打季後賽了嗎?

Halladay’s New Changeup
Yesterday I read that Roy Halladay had changed the grip on his changeup and
was throwing it more often (hat tip to Calcaterra on this one). Before this
year Halladay held the ball in his palm when throwing a changeup, but during
the offseason he worked with pitching coach Rich Dubee and changed to using a
split-finger grip. Let’s see whether we can pick up the difference in the
pitchf/x data. I think it is clearest in velocity-vertical spin deflection
(vertical movement) space.
Definitely a difference: the changeup has about the same velocity but instead
of rising about five inches it now drops a couple of inches. The horizontal
movement on the pitch is also different.
So the different grip imparts different movement on the pitch, so I think it
is fair to say it is a qualitatively different pitch. And Halladay is
throwing the pitch more often. As is noted in the article, before 2010
Halladay was pretty much a three-pitch pitcher (cutter, sinker and curve —
three great pitches), rarely throwing his change more than 5% of the time.
But now he is throwing the change almost 12% of the time. It seems he is much
more comfortable with it.
The results show that Halladay has good reason to be more comfortable with
the pitch. By our linear weights it is worth 1.5 runs per 100, much better
than his changeups in any full year before. Looking at components, the pitch
is wildly more successful, getting 19% swinging strikes per pitch in 2010
compared to 6% in 2009-2007 (pitchf/x years). It also gets more ground balls
(57% GB/BIP versus 55%) and a lower slugging on contact ( 0.452 bases/contact
versus 0.505).
Looking at Halladay’s pitch-count splits, he uses the pitch often when he is
ahead in the count. So it looks like he has developed a second out pitch —
along with his curve — to put batters away when he is ahead in the count.
As Calcaterra noted, it is not like Halladay needed another weapon, but he
has one.
