Head Coach Andy Diver enters his 4th season at Mira Costa High School after a one-year stint at Windward. In his first 3 seasons, he has led the Mustangs to two Bay League Championships and three consecutive CIF playoff appearances. In 2024, the Mustangs finished the season 28-3. A year in which the Mustangs finished Bay League play with a perfect 12-0 record, and 26 game winning streak. The 2024 team finished with the most wins  and the highest winning percentage in school history. The 2024 team finished ranked 1st in the South Bay, 5th  in Southern Section D1, 11th in the State, and 37th Nationally. At the conclusion of the 2024 season, Diver was named the Daily Breeze Coach of the Year, his second time receiving that honor. He is one of only two coaches (Harry Jenkins) to receive that award at two different schools (Mira Costa, Redondo).

In 2017, Coach Diver was named the Head Coach at Redondo Union High School. While at Redondo, Coach Diver helped elevate a program from CIF Division 3 to Division 1. Prior to Covid, his team was ranked 41st in the

country, 8th in the state, and 1st in the South Bay Daily Breeze rankings. 

In 2019, he guided a loaded Sea Hawk team to the CIF semifinals. That team had a 3rd round draft pick and six Division 1 scholarship players on the roster. At the conclusion of the 2019 season, Coach Diver was named

the Daily Breeze Coach of the Year.

​

In 2005, Diver was named the pitching coach at the University of Arizona. He also assisted with recruiting, coordinated UA’s schedule, handles all of UA’s travel plans and road accommodations, and was the co-director of

the Andy Lopez Baseball Academy.

​

Diver came to U of A after spending three seasons as the Head Coach at Los Angeles Harbor Community College where he guided the Seahawks to 75 wins and a pair of South Coast Conference titles in 2002 and 2003. He was named the conference coach of the year in 2003 and sent numerous players on to Division 1 schools and professional baseball. In 2001, he served as the pitching coach for the Mankato Mashers in the Northwoods League.

In his first year at Arizona, he helped guide John Meloan and Kevin Guyette to 10 wins each, the first pair of 10-game winners in the same season at UA since 1979. Closer Mark Melancon tied the school single season record for saves with 11 and in doing so tied the career record of

14 as well. As a group, the 2005 Arizona pitching staff also broke the single season team record for strikeouts with 554 punchouts.

A 1996 graduate of Loyola Marymount University, Diver was a two-year letter winner for the Lions as a pitcher from 1995-96. He transferred to LMU from Harbor where he garnered All-South Coast Conference honors on the mound.

He began his coaching career in 1997 as the pitching coach at his high school alma mater, St. Bernard’s, where he still holds the school records for single season and career victories on the mound. He was also a two time All Daily Breeze selection as Pitcher and 3B. He then spent one

season on the coaching staff at Loyola High School in 1998 before moving back to Harbor in 1999 to serve as the pitching coach. He spent three seasons in that capacity before taking over the program as the head coach in 2002.

Former Mira Costa Head Coach Keith Ramsey played for Coach Diver in American Legion ball at Loyola High and then again for two seasons at LA Harbor.

 “I am honored to be part of the community of Manhattan Beach, employed by MBUSD as an educator, and the Head Baseball Coach at Mira Costa. The tradition of great teams and players is elite throughout the South Bay. We will work hard each day to ensure that tradition of

greatness on and off the field is upheld.”
