After spending four years in the Yankees minor league system, the Mets drafted Billy Murphy in the 1965 rule 5 draft. He made his Major League debut for the Mets on Opening Day 1966 when he pinch ran for Ed Kranepool. He would spend the entire 1966 season appearing in 84 games mainly as a fourth outfielder and pinch hitter. He hit .230 with 3 home runs and 13 RBIs.
Murphy’s best day as a Met occurred on May 13 against the San Francisco Giants when he went 3 for 6 while hitting his first career home run, a three-run shot. Unfortunately, the Mets lost 5-4 in 17 innings.
1966 would be Murphy’s only season in the big leagues, but he did remain in the Mets organization for one more season. He played for the Jacksonville Suns in 1967, the Mets triple A affiliate.
While with the Mets Murphy wore number 23.
