Brandon Short suffered a dislocated left shoulder and torn labrum Thursday after an unsuccessful attempt to catch a deep drive against the Texas Rangers.
The Chicago Tribune reports that the outfielder will undergo surgery and will miss the entirety of his age-23 season.
After a promising 2010 that saw Short post a .365 OBP in Single-A Winston-Salem, Short struggled with Double-A Birmingham, compiling just a .318 OBP. His success at Single-A may have been fueled by some luck, though, as his BABIP sat at a pretty unsustainable .372 with the Dash. That number fell to a more neutral .317 with Birmingham, and his walk rate didn't improve much (5 to 6 percent), leading to his lower on-base percentage.
Short ranked as high as No. 9 on major White Sox prospect lists, although he didn't crack John Sickels' top 20 or Baseball America's top 10.
