Tennis legend who wrote a history of African-American athletes (4)

I believe the answer is:

ashe

(Other definitions for ashe that I've seen before include "tennis champ" , "Arthur, first black Wimbledon men's singles champion, 1975" , "Ex-Wimbledon champ" , "Former tennis star" , "US rallying champion" .)

I've seen this clue in the LA Times.
