※ 引述《dvsmatix (444)》之銘言： : 來源: : mlb.com: http://0rz.tw/dbOm7 : Slugger performed worse during blowouts than close games : By Ed Eagle / MLB.com : 05/17/09 10:49 AM ET : While Alex Rodriguez's admission that he used performance-enhancing drugs : during his tenure with the Texas Rangers ignited a media firestorm, the : allegations by author Selena Roberts in her recent book, "A-Rod: The Many : Lives of Alex Rodriguez," that the slugger was tipping pitches to middle : infielders on opposing teams during blowouts were viewed by many as a greater : blow to the integrity of the game. 在Selena Roberts爆出A-ROD有使用增強表現的藥物之後又爆出A-ROD會打暗號給對手(對方二游) : According to a report in the New York Times, an analysis of Rodriguez's : statistics from 2001-03, and those of opposing middle infielders during that : period, seem to indicate that Rodriguez was not tipping pitches. Or, at the : very least, that any pitch-tipping that was done was extremely ineffective : and counterproductive. 根據NY-TIMES的分析似乎沒有打暗號的問題或是說打暗號根本沒用 : Using a statistical device known as Leverage Index, which was developed by : Tom Tango, the author of, "The Book: Playing the Percentages in Baseball," : Sean Forman of baseball-reference.com compiled data which showed Rodriguez : actually performed better during high-pressure situations than during the : low-pressure situations associated with blowouts. 用來分析的工具Leverage Index 是Tom Tango提出的 Sean Forman 研究指出A-ROD在高壓力的球賽中表現的比較好(跟大比分球賽比的話) 也就是說A-RDO心臟比較大顆 : How does Leverage Index work? According to an example in The Times article, a : hit to lead off the top of the first (an L.I. of 1) has one-third the : significance of a hit with the bases loaded and none out in the top of the : fifth with the home team leading by two (an L.I. of 3), and three times the : impact of a hit with the bases empty and two outs in the bottom of the sixth : with the visitors leading by four (an L.I. of 0.33). 介紹Leverage Index這個工具 : Although the formula is not exactly as simple as determining a batting : average, ERA or OPS (on-base percentage plus slugging), it nonetheless : provides a basis for comparing Rodriguez's success rate in situations of : varying pressures. 雖然Leverage Index不能計算出ERA或OPS 但還是可以比較A-ROD的在不同壓力下的表現 : Forman's research showed that Rodriguez's OPS from 2001-03 was 1.076 in : high-leverage situations, 1.017 in medium-leverage situations and .982 in : low-leverage situations. The data was similar for opposing middle infielders: : an .899 OPS in high-leverage situations, .825 in the middle-leverage : situations and .817 in low-leverage situations. Forman研究數據 A-ROD跟對手的OPS比較 A-ROD 對手高壓 1.076 0.899 中壓 1.017 0.825 低壓 0.982 0.817 : Forman also found that Rodriguez's OPS dropped to .851 when he batted in : games where the team's were separated by seven runs or more, as compared to a : 1.021 OPS when the team's were within six runs of each other. Opposing second : basemen and shortstops posted a .744 OPS in seven-runs-plus games, and an : .840 OPS in all other situations. 另一個數據依球隊分數來算 A-ROD 對手(對方二游) 7+ 0.851 0.744 6分內 1.021 0.840 譯者總結: 別再相信A-ROD關鍵時刻很鳥了不過這篇跟打暗號似乎又扯不上關聯 A-ROD最近窮到只剩下HR 如果翻譯有錯麻煩指教謝謝!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.137.53.186
