Peete is dealing with a concussion at High-A Peoria, Geoff Pontes of Baseball America reports.
It appeared Peete injured his hand on a slide May 13, but this latest report clears up the diagnosis. The 20-year-old outfielder has always been young for his levels and was in the midst of his best stretch above rookie ball (117 wRC+) despite a career-high 31.4 percent strikeout rate.
