Because of all the high school players drafted by the White Sox, there were only a few notable players assigned to the Voyagers, the affiliate the White Sox treat as their "advanced" Rookie Ball club. All of them were pitchers.
RHP Chris Beck, their 2012 second round pick, headed that list. After pitching more than 100 innings for Georgia Southern, the White Sox were careful to manage his professional innings. He was pretty hittable - 51 hits in 40.1 IP. While the offensive environment in the Pioneer League is jacked up and the quality of his defense is questionable, his draft stock fell because he was pretty hittable in his collegiate season, too, so it's a concern. His other main peripherals were good: 36 strikeouts against just 12 walks.
An interesting story was the return of 2010 third round pick, RHP Thomas Royse. He was very impressive for the Voyagers in 2010 before missing all of last year after Tommy John surgery. This time around, he wasn't impressive - 5 GS, 20.2 IP, 32 H, 2 BB, 14 K - before going AWOL again, presumably with an injury.
2012 fourth round pick, RHP Brandon Brennan, also saw himself get hit around. He, too, had his innings managed, evenly splitting his 14 appearances between starting and the bullpen to end up with 37.1 IP, 44 H, 16 BB, 31 K.
