: http://riveraveblues.com/2010/03/how-joba-can-learn-about-reduced-velocity-from-lincecum-25027/
: At this point last year, we began wondering about Joba Chamberlain’s
: velocity. After throwing in the upper 90s out of the bullpen, and then
: mid-90s in the rotation, Joba had been throwing in the low-90s for most of
: spring training. This caused particular concern because Chamberlain had
: missed more than a month in 2008 with shoulder tendinitis. Without his heat,
: would he be as effective a pitcher?
: Clearly, Joba needed to make adjustments if his fastball was to average 92
: instead of 95. He didn’t make them consistently in 2009 and it led to a
: somewhat frustrating season. Now, as we head into a new season, we’re again
: wondering if Joba will recover his velocity, or if he’ll sit in the low 90s
: for the foreseeable future. As long as he can make adjustments with his
: command and secondary pitches his velocity shouldn’t be a problem. For a
: good sample case, we can look to last year’s NL Cy Young winner and the man
: picked 31 spots ahead of Chamberlain in 2006.
: According to the Pitch F/x gun, Tim Lincecum went from averaging 94 mph in
: 2008 to 92.4 in 2009. Yet he struck out hitters at the same clip, gave up
: fewer hits, and walked fewer batters. In other words, he made the adjustments
: necessary to compensate for diminished fastball velocity. He continues to
: work with his new physical realities, and is honing his secondary pitches
: again this off-season. In particular, it looks like he’s working with his
: slider, perhaps with a goal of throwing it more than 10 percent of the time.
: For Chamberlain, the drop-off seems a bit more precipitous. He went from
: averaging 95.2 mph in 2008 to 92.5 in 2009. That might appear to mislead,
: since it counts Joba’s innings as a reliever, where he threw in the upper
: 90s, along with his starts. But he also threw bullpen innings as a reliever
: after the injury and averaged just 93.9 mph there. As a starter, from June
: into August, he averaged 95.1 mph. I don’t think it’s likely that he
: consistently reaches that level as a starter again.
: Even so, his velocity matched Lincecum’s last year. One major difference is
: that Lincecum adjusted by throwing the fastball less often. When it sat 94
: mph in 2008 he threw it 65.5 percent of the time. But with a bit less zip he
: threw it less, just 55 percent. Joba, on the other hand, continued to throw
: the fastball frequently, at 63.3 percent. He also focussed on one secondary
: pitch, his slider, over another, his curve, while keeping the changeup almost
: completely out of his arsenal. Conversely, Lincecum used his two secondary
: pitches, change and curve, about equally. He also worked in his slider 7
: percent of the time, more than Joba used the change.
: Reducing his reliance on the fastball won’t necessarily make Joba a better
: pitcher. After all, if he doesn’t have confidence in his secondary pitches
: they won’t be very effective. But I think that continued heavy use of the
: fastball will present problems for his development. He certainly can succeed
: with it, but he might not be able to do so consistently. And if he can’t do
: that, it’s likely to the pen with him.
Noooote:
1)從春訓中可以發現張伯倫的球，均速已經來到90麥出頭左右，筆者認為，他應該
向盲腸借鏡，不然在可預見的未來，將可能會發生..."不要問，很恐怖"的事...
(經版友指正已修改內文)。
(原po再次查詢相關資料：分別為low-90s / mid-90s / high-90s)
(90出頭 / 95上下 /90幾接近100)
已作更正，有錯誤之處請不吝指教。
2)張伯倫今年的球速降到跟盲腸去年的球速差不多。然而，不同之處在於，盲腸直球
球速降下來，也把它運用的比例減少，搭配更多change & curve ball，
逐年把速球運用的比例縮減，增加其他球種的運用比例，事實證明，並不影響他的
成績，因為這樣的策略之後，他被擊出更少的安打，送出的保送也變少。
3)筆者認為，如果張伯倫依舊過度依賴他的速球，而對其他球種沒有信心的話，
將會對他的發展衍生出很多問題。
by the way...可否請原po把出處註明一下，我想知道這篇出自哪裡，謝謝：）
