Clyde Edward McCullough (March 4, 1917 – September 18, 1982) was an American catcher in Major League Baseball.

Born in Nashville, Tennessee, McCullough batted and threw right-handed and in his playing days stood 5 ft 11+1⁄2 in (1.82 m) (182 cm) tall and weighed 180 pounds (82 kg).

In the anecdote, McCullough comes across as kind, caring and generous, expressing admiration for the contribution of actors to cultural life, and even offering some money to the clearly cash-strapped young trio (and is understanding when it is refused).

He was a key manager and instructor in the Mets' farm system in the mid- to late-1960s when the club developed young pitchers such as Tom Seaver, Nolan Ryan, Jerry Koosman and Tug McGraw.

In 1982, McCullough was serving as the Padres' bullpen coach when he was found dead in his San Francisco hotel room on September 18 during a road trip.
