ARLINGTON, Texas – Team USA has experienced tremendous success in international competition, and to ensure future teams have the highest level of training, the United States Bowling Congress has added seven coaches to the Team USA program.

Joining Team USA head coach Rod Ross and Junior Team USA head coach Bryan O’Keefe on the coaching staff are:

  • Mark Baker, Yorba Linda, California
  • Carolyn Dorin-Ballard, Keller, Texas
  • Andy Diercks, Marion, Iowa
  • Kelly Kulick, Union, New Jersey
  • Mike Shady, Girard, Pennsylvania
  • Bill Spigner, Vernon Hills, Illinois
  • Del Warren, Lake Wales, Florida

The seven assistant coaches will work with the athletes at training camps and will be available to work with the teams in international competitions, as needed. Each coach is an independent contractor for Team USA and not an employee of USBC.

“These coaches bring a wealth of experience to the Team USA program, and the athletes will benefit from the knowledge and experience of this group,” USBC Executive Director Chad Murphy said. “Having the coaches work training camps will help build the coach/athlete relationships. Much like the player selection process for international competitions, we also will make coaching selections for competitions.”

Baker is a USBC Silver coach and former PBA Tour professional who has been coaching for more than 20 years. He has written a bowling instructional book, The Game Changer, and has conducted more than 140 clinics worldwide. He has worked with many PBA players, including current and former Team USA members Chris Barnes, Mike Fagan, Tommy Jones and Bill O’Neill. On the lanes, he won four PBA national titles.
