Wells told PLHS athletic director Alex Van Heuven he needs more time to devote to the many other pursuits and projects he is involved in including his Perfect 33 foundation that provides funds for wounded American soldiers, education and youth sports.
During his four years, his teams compiled an overall record of 67-54, for a winning percentage of .554., winning Eastern League titles the past two seasons.
The Pointers home field at Dana Middle School underwent a $2 million upgrade during Wells' tenure and now features a full artificial turf field and detailed scoreboard that makes it one of the county's top facilities.
The head coaching job has been posted by San Diego Unified School District, but interviews have not yet begun according to Van Heuven.
Wells has expressed interest as staying with the team as pitching coach.
Wells is a 1982 alumni of PLHS. After graduation he went on to post a 239-157 record in 21 years as a Major League pitcher. He threw a perfect game for the New York Yankees in 1998, a feat recently celebrated by the Yankees.
