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.



這篇文章是今年七月時 Martin Perez 大聯盟初次先發後寫的

他首先介紹了 Martin Perez 的小聯盟歷程

2009年他在 Low-A 有驚人的表現 94局 2.31ERA 105K 33BB

升到 AA 之後表現卻相當掙扎

他的表現與球探報告都呈現兩極化的評價

他可以在某場比賽中交出令人敬畏的表現 但下一場馬上讓人失去希望



2011年背傷復原後重新回到 AA

他展現更好的效率 88局 3.16ERA 83K 36BB

卻在升上 AAA 後的10次先發裡交出 49局 72安 6.43ERA 的難堪成績

今年在3A的15場先發的成績是 84局 78安 4.59ERA 49K 38BB

看起來已經可以到大聯盟試試身手了



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的問題是:他非常地不穩定

在他表現好的時候

可以用省力又順暢的動作投出有速度的球

他可以把 92-94 MPH 左右的速球控得很低 來製造出滾地球

他的 curveball 和 changeup 也都讓人印象深刻

他可以用這三種球路製造許多好球 解決掉有一點強度的打線

但當他表現不好時 他的 curveball 和 changeup會無預警失控

當這種狀況發生時 他對速球的 command 也不足以彌補這種情況

為什麼 Martin Perez 的表現會這麼大好大壞?

作者認為他被rush到了

他太年輕就被放到不容許犯錯的環境



作者的對 Martin Perez 未來的預估是

變成最好的投手之一 或持續掙扎 或受傷 或大好大壞

他是ceiling最高的幾個年輕投手之一 但同時floor也相當低

(意指風險很大)
