"When parents and coaches ask me who can really teach and train their 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 is the creator of "RightView Pro."


My goal is to develop skills and prepare players for the next level; teaching proper fundamental baseball and the finer points of the game.  Practices are in the Palos Verdes area - three times a week.  After we start playing games, there will be two practices per week.    Games will be played locally in the South Bay on weekends.  Occasionally, the tournaments take place during three day  holiday weekends.  


Our Club Baseball Teams

- South Bay Stallions coaches are passionate about the amazing

  game of baseball and love teaching kids.

- During our practices and games, It is important to us that our

  players have fun while playing this incredible game. 

- Players on our Club Baseball Team improve and have a blast. 

  When players improve,  they develop confidence, which makes

  baseball even more enjoyable.

- During practice, our baseball coaches teach all aspects of

  baseball to players of all skill levels; from the fundamentals to the

  finer points of the game.   

- Players get a clear understanding of what they need to do in order

  to improve.

- We develop skills and prepare players for the next level.

- Our goal is to have our players reach their maximum potential

- Players benefit from individualized attention and baseball

  instruction in a positive and enthusiastic environment. 

- We provide baseball training in Hitting, Pitching / Throwing

  Mechanics, Fielding of All Positions, Base Running, Situational

  Defense, Catcher's Skills and more.

- Players learn sportsmanship and benefit from positive interaction

  with coaches and the other players.  They gain a respect for the

  game and an understanding of what team work really means, on

  and off the field.

- I would like to emphasize that players should have fun while

  playing this incredible game.  I had fun every time I played and I

  still have fun while coaching.


- We never go over the top with our players.  Baseball is a cerebral

  game and players should be relaxed, prepared, and confident

  while playing the field and up at bat.

South Bay Stallions Club Baseball Teams in PV - Coach Mark Mainini is a former professional baseball player -

"Coach Mainini has worked with my 12 and 10 year old sons for the last three and two years respectively 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

Baseball Video Analysis

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 player sees that he 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.  We provide the appropriate drills necessary to correct the flaws in the swing or delivery.
