The number 51 had only been worn by five Padres before Trevor showed up and ensured that six would be the limit. John Curtis was the first of them in parts of the 1980 through '82 seasons. Fred Kuhaulua also wore it in '81 when Curtis was on assignment. Greg Booker, son-in-law of Padres manager and general manager Jack McKeon, pitched six years of relief in 51 for the Friars from '83 through '89. Don Schulze also donned it in '89. Mike Maddux was the penultimate Padre to have it in '91 and '92. Nobody wore it in '93; Trevor wore number 34 after coming over from the then Florida Marlins. He made the switch to 51 in the spring of '94 and the rest, as they say, is history.
