I became aware of Kerry Dineen's passing through the Summer 2016 edition of USD magazine. He did indeed play baseball, but as one person has alluded to, he played guard on the Chula Vista High School basketball team.
Circa 1970, CVHS played Helix High for the CIF Basketball Championship. Helix had a center named Bill Walton, a 7 footer, while I think CVHS had Don Weimer, who was 6'7" or 6'8". In consequence, Helix won the championship by about 20.
However, in the closing minutes of the game, Walton was dribbling the ball in the key, about chest high. Quick as a flash, Dineen stole the ball, and drove the length of the court for a layup. Quite a moment there in the San Diego Sports Arena. I was 10 at the time; it was quite a thrill.
