Who We Are

Baseball has always been an important part of my life.  My father played in the Phillies Organization for five years and the Yankees Organization for five years.  I Iearned so much from my dad, his teammates, and coaches.  


After youth baseball, my high school team won the New York Championship at Yankee Stadium.  I played college ball in Florida at Miami Dade for a short time.  While playing in the Colonial League and the Stan Musial League on the east coast, Joe Torre invited me to Shea Stadium for private workouts with Joe Torre and Rube Walker of the New York Mets.  Rube Walker was the pitching coach at the time.  He coached Nolan Ryan, Tom Seaver, Jerry Koosman, and Phil Niekro.  I was recruited as an outfielder / pitcher by the Winter League in Puerto Rico and signed shortly thereafter with the Cleveland Indians organization.  When released due to injury, I continued playing until I was 31, for the love of the game.  Tommy Lasorda had me throw batting practice to his Los Angeles Dodgers when they played at Shea.  


I married my high school sweetheart, Madelon, who among other things, played softball for the love of the game until she was thirty years old on one of the most competitive teams on the east coast.  We were blessed with a daughter and two sons.  I coached their baseball teams and All Star teams in Palos Verdes and Torrance.  I coached their soccer and softball teams in Palos Verdes.  Our family loves sports and we enjoy them together.


I have been head coach for many regular season teams, All Star Teams, and club teams  in southern California, including the Pirates and currently the South Bay Stallions.  I was a  coach for the South Bay Seals and the South Bay Seahawks.  In 2004, I was a coach of the Palos Verdes Peninsula High School team.  


In addition to coaching teams, I have taught baseball professionally in the South Bay of southern California for many years.  Many of the players have played college baseball and some have played professionally.  I have run many baseball camps as well as baseball clinics for players and coaches for many years.


I worked with Don Slaught for many years.   Don Slaught is a sixteen year Major Leaguer, hitting coach of the 2006 American League Champion Detroit Tigers.  I was there during the inception of his creation, "RightView Pro", a unique, state of the art instructional video analysis system where players can see themselves hit in side by side video synchronization with the best hiters in the game.  Players are able to see what the best hitters ALL do.  I have used this system with my students for many years.  I have worked with Don, representing "RightView Pro" at many conventions, from MLB to NCAA, etc., spring training with the Chicago White Sox, I shot video of baseball swings at All Star games for the "RightView Pro" system, and taught baseball and softball coaches from around the country how to operate the "RightView Pro" video analysis system.


I have also worked with many softball players at training facilities, including Bat Masters in Beaumont, Texas, where I had the opportunity to work with twenty two high school softball players over a period of time.  Eighteen of them were offered full athletic scholarships to the most competitive colleges in the country.  


I currently teach baseball and softball privately in the Palos Verdes area, (south bay of southern California), and in Nederland, TX (southeast Texas - near Beaumont, TX), to players of all ages and skill levels - Little League, Pony, Club, High School, and College Baseball Players.  We run baseball camps and clinics in Palos Verdes, CA / Los Angeles - near Torrance, Redondo Beach, Lomita, San Pedro, and Long Beach, as well as coach teams locally.  We provide baseball instruction in all aspects of baseball; from the fundamentals to the finer points of the game. I also coach club baseball teams in southern California, the South Bay Stallions.  My passion for the game still grows to this day.   


Teaching baseball is so gratifying.  I truly enjoy it and can't imagine my life without it.


My family and I have made wonderful, life long friends in the baseball communities of the South Bay.

Professional Baseball Instructor Mark Mainini

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."
