Mark Mainini - Baseball Coach

"When parents and coaches ask me who can really teach and train their baseball players or teams, I recommend Mark Mainini."

                                      Don  Slaught 

- Don Slaught, aka "Sluggo", played in the Major Leagues for  sixteen years, was the hitting coach of the 2006 American League Champion Detroit Tigers, and creator of "RightView Pro".


Video Swing Analysis & Pitching Analysis

Baseball Video Analysis during private baseball instruction - Our players benefit from seeing themselves in side by side synchronized video with the best hitters and pitchers in the game.  We provide video analysis, explanations, demonstrations, and implement the appropriate drills in order to improve their efficiency.  Slow motion visualization and frame by frame breakdowns make it possible for us to point out what the best hitters ALL do - the specific and essential aspects of the swing which make them the most mechanically efficient.  If a hitting student sees that he or she is doing something different compared to all the Major Leaguers, the student then has a visual concept of the adjustments that need to be made. 


Online Baseball Video Analysis:  It's easy.  Just email digital video of the player while hitting or pitching to us and we will respond with an evaluation, swing analysis and / or pitching analysis, pointing out specific aspects of the swing or delivery that need attention, as well as the reasons why.  We will then recommend the appropriate drills designed for the specific aspects of the swing or delivery.




Baseball Trainer

"Coach Mainini has worked with my 12 and 10 year old sons through club baseball and private lessons.  They are both better pitchers and improved hitters, who have an improved command of situational baseball and now own an understanding of the finer details of the game of baseball.  My boys are huge fans of Coach Mark, not only because of what he teaches them, but how he interacts with them.  He has contributed significantly to their love of the game."

                                                               - Richard Rosas


"I have known Mark for about 8 years. I met him through Don Slaught at a three day baseball convention in Texas.  I was so impressed wirh his knowledge and teaching skills that I arranged for him to fly to a newly constructed 6000 sq. ft. indoor hitting facility in Beaumont, TX  many times.  I wanted Mark to train my instructors as well as myself.  He was magic with the students of all ages 6-20 with his ability to have confidence, encouragement and patience with each student at their own skill level.  My daughter, who was a student of Mark's has flown out twice from Beaumont, TX  to Los Angeles to train with Mark as we feel it's the best coaching has to offer for her future hitting lesson future."
