One of the most important things that separates a future starter and reliever is the number of pitches the pitcher can throw. A reliever only needs one or two dominating pitches because it's unlikely he'll see the same batter in a game more than once. A starter doesn't have that luxury and needs to have several pitches in order to keep the hitters off balance. A sharply thrown slider might strikeout a hitter the first time, but major league hitters learn quickly and the next time they see that slider they may hit it for a home run. Thus future starters usually command around 4 pitches. Rarely do you see a pitcher like Chien-Ming Wang who more or less gets by with only two pitches simply because his sinker was so dominant.

如何評估小聯盟投手的潛力 系列二(翻譯)

所在層級的競爭強度
當我們在評估一個投手潛力的時候,切記不要只著重帳面上的數據。我們還要審視這投手所面對的打者群背景,再來綜合評判這些數據的意義。拿一個22歲剛剛大學畢業的投手作舉例,如果把他放在低階1A來面對這些高中年紀的打者,很明顯的你可以預見這名投手將可以主宰整個局面。這投手應該已經有豐富的面對打者作戰經驗,而這些打者搞不好連一顆夠水準的變化球都沒看過或是還在學習對戰的理論。相反的,如果一個年輕投手表現的跌跌撞撞,或許是因為被放到了過高的層級,而不是投手本身的成長限制有問題。李振昌和羅嘉仁赴美之前就已經有豐富的大專和國際賽經驗,就如同預期的,他們在一開始的高階1A就表現得非常的好。

A guide to evaluating pitching prospects part II
It's important not to evaluate the statistics of a pitching prospects in a vacuum. Who the pitcher is pitching against is important to gain some context for his statistics. For example, a 22 year old pitcher out of college has a good deal of experience against sound hitters. Place him on a low-A team against high school aged players who have probably never seen a good breaking ball or even thought about game theory and you would expect the pitcher to dominate. Conversely, if a young pitcher is getting rocked and a high level that is not always cause for alarm since he might be in over his head. Chen-Chang Lee and Chia-Jen Lo both came to the states with college and international experience and, as expected, did very well when they started in high-A.

因為受到太多的巨大變數或很嚴重受傷的影響,投手的潛力是非常非常難預測的。儘管如此,我們還是可以規劃出一些主要特點來幫助定義最佳的潛力投手。同時我們也會來檢測一些可能會蒙蔽我們判斷的數據,看看它們是如何幫倒忙的。

陳鴻文算不算頂級潛力新秀?(翻譯)
(原文請參考本站文章 Is Hung-Wen Chen a top prospect?)
陳鴻文這一季的表現非常強眼,他的防禦率只有低到2.27的水準。在2A能夠有這種防禦率表現的,通常很快的就會被評定為頂尖明日之星。就讓我們進一步檢視他這一季的表現,再來評論他夠不夠格被稱為頂尖的明日之星。
