http://tinyurl.com/27xvz5 By Alex Eisenberg Month 25, 2008 One of the big mysteries of the 2007 season was the decline of Pirates' OF Jason Bay. The question everybody has is how it happened. Was it injuries? Bay did battle knee discomfort for much of the 2007 season and was coming off arthroscopic knee surgery from the previous offseason. However, Bay has said his knee only bothered him when playing the field and had no effect on his season. Did he just have a down year? Another possibility. Perhaps he has just begun his decline as players with his skill set seem to decline at a faster and earlier rate. Lets begin with his numbers from the last two seasons: 2006 - .286 BA, .928 OPS, 15.2 BB%, 27.4 K%, .246 ISO, .338 BABIP, 15.6 LD%, 40.4 GB%, 3.8 IFFB%, 18.8 HR/FB% 2007 - .247 BA, .746 OPS, 9.9 BB%, 26.2 K%, .171 ISO, .298 BABIP, 16.5 LD%, 38 GB%, 9.8 IFFB%, 11.4 HR/FB% 去年賽季最大的謎團之一是Jason Bay的不振。揪竟~~這是為什麼呢？是受傷嗎？Jason Bay去年確實一直有膝蓋問題的困擾，在季前也曾動了膝蓋關節鏡手術。然而，他表示膝蓋問題只有在守備時有影響。只是因為單純的低潮嗎？有可能。或者是，也許他只是到了該衰退的年齡？我們先從Jason Bay過去兩年的成績談起吧。 2006 - .286 BA, .928 OPS, 15.2 BB%, 27.4 K%, .246 ISO, .338 BABIP, 15.6 LD%, 40.4 GB%, 3.8 IFFB%, 18.8 HR/FB% 2007 - .247 BA, .746 OPS, 9.9 BB%, 26.2 K%, .171 ISO, .298 BABIP, 16.5 LD%, 38 GB%, 9.8 IFFB%, 11.4 HR/FB% What do the statistics tell us? 1. Loss of power - 75 point loss in ISO-power and a decline in the percentage of fly balls that became HRs (18.8% to 11.4%) 2. Softer contact - lower batting average and a lower BABIP (batting average on balls in play) 3. Decline in plate discipline - he may not have seen the ball all that well out of the pitcher's hand or he felt uncomfortable hitting with two strikes due to a drop in confidence 4. Similar batted ball data - Bay hit a similar about of GBs and FBs, while his LD% went up slightly. His IFFB% moved more toward the league average. 數據告訴我們什麼？ 1.爆發力的衰退 - ISOP有75趴的減少，同時HR/FB比也下降。 2.更差的擊球率 - 更低的打擊率和BABIP。 3.揮棒自制能力的退化 - 可能他看不清楚投手投出的球路或是在兩好球時信心下降。 4.相似的打擊內容 - Bay的滾球和飛球率在這兩年很接近，而且平飛率還上升一些。他的 IF/FB更接近聯盟平均。 The clip on the left is of Bay in 2006 and the pitch is a 92 mph fastball that drifts back over the middle of the plate. The clip on the right is of Bay during the 2007 season and the pitch is an 89 mph fastball with a little sink that also drifts back over the middle of the plate. I've done my best to synchronize the clips to contact, but if the clips seperate from one another, just refresh the browser and the clips will start over again. Both pitches were hit for HRs between left and center field. So what differences do you see if any at all? My first general observation is that he seems a bit more together in 06. The bat is closer to his body and the arms have a little bit more of a bend to them . What I specifically want to look at is his stride into foot plant. It looks as if the 07 Bay reaches his front leg forward as he lifts and drops his foot into foot plant, while the 06 Bay seems to glide into foot plant without reaching. 左邊那段短片是2006年的Bay面對一顆92 mph的紅中速球。右邊那段式2007年的Bay面對一顆89 mph的紅中速球帶點下沉尾勁。這兩顆球都被打成中左外野的全壘打。所以，你看到了什麼？首先，我最先注意到的是他在06年的協調感覺比較好。球棒比較靠近身體同時手臂弓得比較多。我特別注意到他跨步。07年的Bay看起來像他只是踏出一步，但06年的跨步比較有些滑行的感覺。 The two clips above are of Bay from toe touch into foot plant. They both seem to carry their wieght forward a similar distance. However, the problem is with his timing and efficiency. Look at Bay in 06...see how at the very end of the clip, the point in which his foot plants, his hips have begun to rotate and the hands are about to come with it? Bay's 2006 swing has much better efficiency of the power-producing components that go into a swing. Use the belt buckle as an indicator. The chain of events that lead to Bay's swing look much more smooth and efficient in 2006 than 2007. As each version begins to rotate their hips, which looks to have the more violent/aggressive rotation of their hips? Which version puts more force into their swing? 這兩段是腳掌著地的過程看起來很接近。然而，問題是在於timing and efficiency。有沒有看到，06年的Bay，在腳掌著地的一剎那間身體開始轉動，手開始帶進來？06年Bay的揮棒有比較好的效率。利用腰帶扣當做指引。這整個連鎖反應使Bay在06年的揮棒比起07年更加平順、有效率。在啟動旋轉的過程中，哪個旋轉看起來更有侵略性？哪個版本看來揮棒使力較多？ To me, it looks like the 06 version has a much more powerful hip rotation. Bay's 2007 swing doesn't build up as much momentum and force as his 2006 swing does. To see a powerful hip rotation, all one has to do is look at what Prince Fielder does. I think part of the problem is that he extends that front leg forward and hurts his ability to efficiently rotate his hips like he does in 06. Also, if you go back and simply look at each version before he swings, you see a lot of unnecessary movement in the 07 clip. The bat is the key indicator to look at. 在我看來，06年的版本臀部的扭轉有更多的力道。07年的Bay的揮棒沒有製造出相當於06年揮棒的動量和力道。關於臀部的扭轉，可以參考Prince Fielder的示範。我想扭轉的問題有一部分是因為前腳的過度伸展，這削弱了Bay臀部扭轉的效率。另外，假使你在簡單的回去瀏覽之前的影片，你可以看到07年的Bay做了很多不必要的動作，球棒是很好的線索。 Getting Jason Bay Back On Track Well, I first think this goes beyond mechanical problems. If you read certain quotes from Bay during his slump, you will hear him talk about a feeling of uncomfortableness. He said something to the effect of finding himself in an 0-2 hole and having the feeling the at bat was already over. His confidence is the first thing he must correct. When the pitch is thrown, the batter has less than a second to see the ball, determine pitch type, determine the pitch location, and decide whether to swing the bat or not. There is no room for thinking about mechanics. The more a player thinks, the worse they do. Once he fixes himself mentally, he should go to work on his mechanics. He first needs to shorten his swing a little. Get into a more compact, more together position like he had in 2006. Bay should then work on his stride into foot plant so that he efficiently maximizes the power of his swing. Of course, this is all easier said than done. We'll revisit this article later to see what adjustments, if any Bay makes. 回到原來的Jason Bay 嗯，我首先想到的不是動作上的問題。如果你有聽說過Jason Bay對自己低潮的評論，你會聽到很多不舒服的話。他說當在0-2的時候總有不知名的困擾使他覺得這個打席已經完蛋了。他需要先建立起信心。當球投出後，打者只有不到一秒的時間看到球、辨識球路種類、決定要不要攻擊。沒有時間去想東想西。想的愈多，打的愈差。建立信心後，他需要修正一些動作。更簡短的揮棒。更多的衝量、更好的協調，像他在06 年做的那樣。接下來再把跨步做好。當然，說的總是比做的簡單。假如Bay有做些什麼修正的話，我們會再回顧這篇文章。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.5.3
