At D-BAT Tulsa, lessons are taught with the ballplayer as the focus while involving the parents during the lesson.  We have great instructors who can instruct players at every level for improvement.  However, our instructors can not be at the ballplayer's games, so they rely on the parents for feedback on how the player is doing in game situations.  

We are proud to have CJ Medlin, Mark Roberts, Michael Walker, Krystel
Markwardt, Tim Burton, and Matt Frazier as part of the D-BAT family.

CJ MEDLIN

where he was a 1st Team All-American Catcher, hitting .400 with 25
Home Runs and 86 RBI’s. After his time at Seminole, CJ signed with the
University of Alabama before being drafted by the Chicago Cubs. He
played more than 6 seasons of professional baseball for the Chicago Cubs
and the Milwaukee Brewers, including AAA ball. CJ has been taught by
experienced instructors, such as major leaguer Ivan Rodriguez, and uses
this experience in his own instructions today. CJ brings experience in
hitting, catching, and pitching instruction and comes highly recommended
by colleges and scouts. He is also a certified strength and conditioning

in a new direction- coaching and instruction. He has been training kids
for more than six years and has coached at the high school level for three
