1971 Topps #577 Jim Lonborg
About Jim Lonborg
Lonborg spent part of 1971 at Triple-A Louisville before finishing 10-7 with a 4.13 ERA for Boston. On October 10, he joined George Scott, Ken Brett, Billy Conigliaro, Joe Lahoud and Don Pavletich in a trade to Milwaukee for Tommy Harper, Marty Pattin, Lew Krausse and Pat Skrable. His Red Sox card is fifth-series #577.
Jim Lonborg studied biology at Stanford and played summer baseball on teams sponsored by the Orioles before signing with Boston for $25,000 in 1963. His father taught agriculture, and Lonborg originally hoped to become a surgeon. Nicknamed Gentleman Jim for his quiet, friendly manner, he became the first Red Sox pitcher to win a Cy Young Award. In the 1967 World Series he threw a one-hit shutout in Game 2 and a three-hit complete game in Game 5 before losing the deciding game on two days of rest. His major league career lasted 15 seasons, continuing with Milwaukee and Philadelphia, and ended with 157 victories. After baseball, he graduated from Tufts dental school in 1983 and practiced in Hanover, Massachusetts. The Red Sox inducted him into their Hall of Fame in 2002.
