His only season as a full-time regular was with the 1964 Washington Senators under manager Gil Hodges, primarily as a third baseman, but also playing at shortstop and second base. Kennedy hit .230 with seven home runs and 35 runs batted in (RBI) in 148 games.[2] After the 1964 season, he was traded with pitcher Claude Osteen and cash to the Los Angeles Dodgers for five players, including outfielder Frank Howard.[2] With the Dodgers, Kennedy would be part of history when he replaced Jim Gilliam at third base in the eighth inning of Sandy Koufax's perfect game on September 9, 1965. Kennedy did not get to bat in that game, nor did he have a fielding chance as Koufax struck out the last six Chicago Cubs he faced to complete his then-record fourth no-hitter.[3] The New York Yankees acquired Kennedy in a trade after the 1966 season, then sold him to the expansion Seattle Pilots after the 1968 season.[4] Kennedy retired in 1974 after four and a half seasons with the Boston Red Sox.[2]
Retirement
Kennedy scouted, managed, and coached in the minor leagues after leaving Major League Baseball. He managed the North Shore Spirit through most of their five years as an independent team, and was named the Can-Am League Manager of the Year in 2006.[5]
