According to Ocala.com, Summers died after a lengthy battle with kidney cancer in Ocala, Fla.
Summers was a Vietnam veteran before the Oakland A's signed him as an amateur free agent at age 25. He made it to the big leagues three years later and had stints with the Cubs and Reds before Sparky Anderson brought him to Detroit in a midseason trade.
Summers thrived as an outfielder upon arrival, homering 20 times over 90 games in 1979 while batting .313 with 62 RBIs. He followed that up with a move to DH, batting .297 with 17 homers and 60 RBIs in 1980.
The Tigers traded Summers to San Francisco in the spring of 1982 for Enos Cabell. Summers faced the Tigers in the 1984 World Series as a member of the Padres.
