Below, is a summary of the comp study on 8 sophmore players by The Harball Times. I'm also including the link to the entire article.
http://www.hardballtimes.com/main/article/eight-sophomores/Eight position players made their big-league debuts in 2009 and collected at least 400 plate appearances. I thought it would be interesting to go back through history in search of analogous players so that we might get some sense of what to expect going forward from these eight.
The basic approach was to identify players who debuted at the same age and who put up similar numbers, then see how those players' careers progressed. We'll look at each of last year's debutantes and their analogs in descending order of OPS+.
Here's the excerpt on Cutch.Andrew McCutchen, Pittsburgh Pirates, CF, age 22
493 PA, .286/.365/.471, 122 OPS+
Fewer 22-year-olds meet our criteria: seventy-three, to be precise, from Charlie Keller (.334/.447/.500, 143 OPS+ in 1939) to Pee-Wee Wanninger (.236/.256/.305, 43 OPS+ in 1925). Like Coghlan, McCutchen is eighth on our list (third among active players, behind Austin Kearns and Evan Longoria).
The most similar player to McCutchen here is an odd one. Some of their rookie numbers (BA, 2B, HR) are nearly identical, and the comp was a terrific player, but it's just that... well, McCutchen doesn't remind me at all of Will Clark:
Player Year Pos PA BA OBP SLG OPS+ BB K
McCutchen 2009 CF 493 .286 .365 .471 122 54 83
Clark 1986 1B 458 .287 .343 .444 121 34 76McCutchen exhibited more power and better plate discipline while playing a more difficult defensive position. Overall, he was even better than Clark, who retired with a .303/.384/.497 (137 OPS+) line and more than 2,100 hits. That's it, send McCutchen to Cooperstown now. Right?
Well, no. This is a fantastic start, but did I mention Austin Kearns?
Player Year Pos PA BA OBP SLG OPS+ BB K
McCutchen 2009 CF 493 .286 .365 .471 122 54 83
Kearns 2002 RF 435 .315 .407 .500 134 54 81Including players who came up before age 22 gives us a few more names, but none neccesarily a better fit than Clark. The closest are probably Paul Molitor, Grady Sizemore, and Gary Matthews Sr. For grins:
Player Year Pos PA BA OBP SLG OPS+ BB K
McCutchen 2009 CF 493 .286 .365 .471 122 54 83
Molitor 1979 2B 645 .322 .372 .469 126 48 48
Sizemore 2005 CF 706 .289 .348 .484 123 52 132
Matthews 1973 LF 605 .300 .367 .444 120 58 83Molitor had a full season under his belt before age 22, which... what a difference a year makes. Regardless, McCutchen is keeping nice company at such a young age.
