翻得不好的地方还请多帮忙 Prospect of the Day: Martin Perez, LHP, Texas Rangers The Texas Rangers promoted rookie Martin Perez to the major leagues last week. He made his first major league start against the Oakland Athletics on Saturday, going 5.1 innings, giving up six hits, a walk, and two runs, fanning five. The young southpaw is one of the better pitching prospects in baseball, although he isn't an easy one to analyze. Perez was signed by the Rangers in 2007 from Venezuela, earning a bonus of $580,000. His pro debut was successful, with a 3.65 ERA and a 53/28 K/BB in 62 innings for Spokane in the Northwest League in 2008 at age 17. He remained very effective for Low-A Hickory in 2009, posting a 2.31 ERA in 94 innings with a 105/33 K/BB ratio. However, the Rangers promoted him to Double-A late in the year, and not unexpectedly he had some problems, posting a 5.57 ERA in five starts. Returning to Double-A Frisco in 2010 at the tender age of 19, he struggled, posting a 5.96 ERA with a 105/50 K/BB and 117 hits allowed in 100 innings. His performance and his scouting reports were very inconsistent; he would look awesome in one start and hopeless in the next. He also missed time with a back injury. Returning to Frisco to begin 2011, he was much more effective, posting a 3.16 ERA in 88 innings with an 83/36 K/BB. However, he got crushed again after being promoted to Triple-A, posting an ugly 6.43 ERA in 10 starts for Round Rock, with a 37/20 K/BB and a disturbing 72 hits in 49 innings. Perez made 15 starts for Round Rock this spring, going 5-5, 4.59 with a 49/38 K/BB in 84 innings with 78 hits allowed. The K/IP ratio is unimpressive and he had his share of bad outings, but he looked good often enough for the Rangers to move him to the majors. 这篇文章是今年七月时 Martin Perez 大联盟初次先发後写的 他首先介绍了 Martin Perez 的小联盟历程 2009年他在 Low-A 有惊人的表现 94局 2.31ERA 105K 33BB 升到 AA 之後表现却相当挣扎 他的表现与球探报告都呈现两极化的评价 他可以在某场比赛中交出令人敬畏的表现 但下一场马上让人失去希望 2011年背伤复原後重新回到 AA 他展现更好的效率 88局 3.16ERA 83K 36BB 却在升上 AAA 後的10次先发里交出 49局 72安 6.43ERA 的难堪成绩 今年在3A的15场先发的成绩是 84局 78安 4.59ERA 49K 38BB 看起来已经可以到大联盟试试身手了 Perez is a 6-0, 180 pound left-handed hitter and thrower, born April 4, 1991 in Guanare, Venezuela. I've seen him pitch several times over the last four years. On his best days, he looks like a pitcher should look: with a low-effort, clean and smooth delivery that generates easy velocity. At his best, he works at 92-94 MPH, topping out at 96, usually keeping the fastball low and picking up ground balls. His curveball and changeup are both very impressive pitches, at their best. When he's going well, he throws three plus major league pitches for quality strikes, and mows through a lineup with little difficulty. The problem is, Perez is very inconsistent. Some days, he looks like a number one starter. Other days, he's lucky to escape the first inning. Although he usually maintains his velocity, he loses the touch with the curveball and changeup without warning, and his fastball command isn't good enough to compensate when that happens. On good days he demonstrates excellent pitching instincts and beyond-his-years mound presence. On bad days, he looks like a lost, confused, thrower. Why is he so erratic? It is hard to say, except that you can usually tell if it is going to be a bad day for him very quickly. I think the biggest issue is that he's simply been pushed very rapidly, and the Rangers have promoted him at the earliest plausible moments. Perez has been very young for his leagues, and neither the Texas League nor the Pacific Coast League are forgiving environments. Neither is the American League. You can draw a scenario where Perez develops into one of the best pitchers in baseball within two years. He could also struggle for awhile, or get hurt, or remain as erratic as he currently is for the rest of his career. He has one of the highest ceilings of any young pitcher in the game, but his floor is quite low as well. Martin Perez的问题是:他非常地不稳定 在他表现好的时候 可以用省力又顺畅的动作投出有速度的球 他可以把 92-94 MPH 左右的速球控得很低 来制造出滚地球 他的 curveball 和 changeup 也都让人印象深刻 他可以用这三种球路制造许多好球 解决掉有一点强度的打线 但当他表现不好时 他的 curveball 和 changeup会无预警失控 当这种状况发生时 他对速球的 command 也不足以弥补这种情况 为什麽 Martin Perez 的表现会这麽大好大坏? 作者认为他被rush到了 他太年轻就被放到不容许犯错的环境 作者的对 Martin Perez 未来的预估是 变成最好的投手之一 或持续挣扎 或受伤 或大好大坏 他是ceiling最高的几个年轻投手之一 但同时floor也相当低 (意指风险很大) 来源:http://www.minorleagueball.com 发表时间 JUL 3, 2012 --
