"Good Morning America" co-anchor Robin Roberts was honored with the Arthur Ashe Courage Award at Wednesday night's ESPY Awards.

Roberts underwent a bone marrow transplant last fall to treat a life-threatening blood and bone marrow disease.

She was off work for five months before returning to her TV job. LeBron James presented Roberts with the award, and first lady Michelle Obama saluted her via video.

Roberts received a standing ovation and noted her friendship with the late Ashe. "At this moment I'm filled with such gratitude," she said.

LeBron James won three ESPY Awards, including male athlete of the year. Serena Williams won two awards, including female athlete of the year.

Texas A&M quarterback Johnny Manziel won male college athlete honors after flying in earlier from Hoover, Ala., where he attended SEC media day.

Baylor's Brittney Griner, who now plays for the WNBA's Phoenix Mercury, won female college athlete.

The best game was Game 6 of the NBA finals between the Heat and San Antonio Spurs. The winners in most categories were determined by fan voting.
