Relief pitcher may be the most expendable position on a major league ball club. With a few exceptions (such as Hoyt Wilhelm, Roy Face and Lindy McDaniel), most relievers cannot extend top performance season after season.
Don McMahon was one of those exceptions – a standout reliever for 7 different clubs over an 18-year career. Only once did he lead the league in any pitching category, but you could count on his durable arm and pitching savvy for a full season of putting out fires.
McMahon was signed by the Boston Braves in 1950. His major league debut was delayed by military service and 5 years of minor league seasoning. But when he finally made it to the Braves, he did it in a big way: Appearing in 32 games for the 1957 World Series champions, McMahon went 2-3 with a 1.54 ERA and 9 saves. In 1958, he was selected for the National League All-Star team on the way to a 7-2 season with 8 saves. In 1959, he led the league in games finished (49) and saves (15) with a 5-3 record and 2.57 ERA.
McMahon spent 6 seasons with the Braves, appearing in 233 games and tallying 50 saves with a combined ERA of 3.34. In May of 1962, he was purchased by the Houston Colt .45’s, where he toiled for 2 seasons (6-10 with 13 saves and a 2.81 ERA) before being purchased by the Cleveland Indians. In 3 years with the Tribe, McMahon appeared in 140 games, posting a combined record of 10-8 with 28 saves and a 2.81 ERA.
In June of 1966, the Indians traded McMahon and pitcher Lee Stange to the Boston Red Sox for Dick Radatz. Again he was effective (11 saves and a 2.82 ERA in 60 appearances) and again he was traded – this time to the Chicago White Sox for infielder Jerry Adair. McMahon spent a “split” season with the White Sox in 1967-1968, going a combined 7-1 with a 1.77 ERA in 77 appearances.
He was then traded to the Detroit Tigers (for pitcher Dennis Ribant) where he appeared in 54 games over parts of 2 seasons, going 6-6 with 12 saves and a 2.97 ERA.
In August of 1969, McMahon was dealt to the San Francisco Giants. He followed with 2 of the best seasons of his career. He appeared in 61 games both seasons, going 9-5 with 19 saves in 1970 (2.96 ERA) and 10-6 in 1971 with 4 saves. But the juice finally began to fade from his arm. McMahon appeared in only 44 games in 1972 and only 22 in 1973. He was released by the Giants during the 1974 season.
McMahon finished his career at 90-68 with a 2.96 ERA. At the time he retired, his 874 career appearances (all but 2 in relief) were the fourth most all-time after Wilhelm, McDaniel and Cy Young.
