White Sox announce 2015 player development staff

The Chicago White Sox have announced their player development staff and assignments for the 2015 season. 

Joel Skinner at Class AAA Charlotte (fourth season), Julio Vinas at Class AA Birmingham (third) and Mike Gellinger with the Arizona Rookie League White Sox (second) return to manage their respective clubs in 2015. Tommy Thompson begins his third stint (2011, '13) with Class A Kannapolis after managing Class A Winston-Salem in 2014.

New managers in the organization include Tim Esmay at Winston-Salem and Cole Armstrong at Advanced Rookie Great Falls. Esmay spent the previous five seasons (2010-14) as the head coach at Arizona State University, where he led the Sun Devils to four NCAA Tournament berths and an appearance in the 2010 College World Series. He also served as the head coach at the University of Utah from 1997-99.

Armstrong enters his first season as a manager at the professional level after serving as the hitting coach with the AZL White Sox in 2014. He played 10 minor-league seasons, including five in the Chicago system (2006-10), batting .259 (589-2,270) with 65 home runs and 314 RBI.

Margaret Rall begins her second season as the head trainer with Great Falls after joining the club prior to the 2014 season. She is the first female, full-time, on-field staff member to work for the organization. Prior to joining the White Sox, Rall worked for teams at the collegiate, minor-league and independent levels, including stints with the Advanced Rookie Kingsport Mets and the Gulf Coast League Red Sox.

Pitching coaches Richard Dotson (Charlotte), Britt Burns (Birmingham), J.R. Perdew (Winston-Salem), Jose Bautista (Kannapolis), Brian Drahman (Great Falls) and Felipe Lira (AZL White Sox) will return to their posts this season. 

Nick Capra enters his fourth season as the White Sox director of player development, and Kirk Champion will serve as the organization's field coordinator for the fourth consecutive season.
