Cubs' Colvin: Nice power, but still raw
The 24-year-old outfielder was seen as a bit of a reach when he was drafted 13th overall in the 2006 draft out of Clemson. While he put up some decent seasons in the minors over the past four years, he never really had that one big season that made you really take notice. He slugged .488 between two levels in 2007, but it came with just 15 walks versus 101 strikeouts in 92 at-bats. He was hampered by a bad elbow in 2008 that prevented him from getting full extension with his swing, and he posted just a .424 slugging percentage at Double-A, then required Tommy John surgery after the season. Last year he slugged .480 between high Class A and Double-A while hitting .286, but scouts were still concerned about his plate discipline. His career on-base percentage in almost 1,900 minor league plate appearances, none of them above Double-A, was just .320 entering the season.
