As coach John Junior "Champ" Summers (June 15, 1946 – October 11, 2012) was an American Major League Baseball outfielder and first baseman for six teams during his eleven-year career that spanned from 1974 to 1984.

Summers, who was born in Bremerton, Washington, served in the United States Army in the Vietnam War and was a recipient of the Purple Heart, did not play his first Major League Baseball game until he was 28 years old.

He was signed by the Oakland Athletics as an amateur free agent in 1971, after being discovered in a men's softball league following his service in Vietnam.

But Summers' biggest hit of the season was a pinch-hit grand slam on April 10, 1984, off of St. Louis Cardinals right-hander Bob Forsch propelling the Padres to a 7–3 victory en route to a sizzling 10–2 start and runaway capture of club's first division title.

[citation needed] Summers ended his career playing for the Padres in the 1984 World Series against his former skipper, Sparky Anderson, and his former Detroit Tigers teammates.
