Retired footballer Diego Forlan lost 6-1 6-2 in 47 minutes on his professional tennis debut in a doubles event in his native Uruguay.
The former Manchester United and Atletico Madrid striker, 45, and Argentine partner Federico Coria lost to Bolivian pair Boris Arias and Federico Zeballos after receiving a wildcard for the Uruguay Open in Montevideo.
The tournament was on the ATP Challenger Tour – the level below the main ATP Tour.
Both Forlan and Coria and their opponents held serve to start the match, but Arias and Zeballos quickly pulled away after earning a break in the third game of the first set.
