This is not the first time Duda has had wrist problems. As a freshman at USC, he broke his left wrist on a collision at first base back in 2005. He went on to hit just .208/.322/.299 in 91 PA over 34 games that year as a 19-year old. His sophomore year, his batting average and his OBP rose, but his power did not as he hit .298/.391/.398 in 226 PA over 56 games. By his junior year, he hit for a little more power: .280/.378/.468 in 223 PA over 53 games.
Here's his College Isolated slugging, calculated by subtracting batting average from slugging to measure a batter's power, by year:
Fr. ('05) - .091
So. ('06) - .100
Jr. ('07) - .188
The next time he hit for an isolated slugging above .180: 2010 when he "broke out" with a .304/.398/.569 line in 495 PA between AA Binghamton and AAA Buffalo as a 24-year old that earned him his big league debut.
How analogous are Duda's two wrist injuries separated by over seven years and many professional paychecks? I do not know precisely. The hands (top and bottom) do different things in a player's swing, but a batter needs both. Also, Duda's collegiate improvement was likely a result of both improving health and physical and mental development.
