Tennis legend Pete Sampras will make his latest competitive appearance against Petr Korda in Boston on 3 May.
Sampras won a record 14 Grand Slam titles in his career
The 35-year-old American will play in the Champions Cup Boston, part of the Outback Champions Series for over-30s.
Sampras will first face former Australian Open champion Korda and will also take on John McEnroe on 5 May.
The seven-time Wimbledon champion retired after winning the US Open in 2002 and appeared in the World Team Tennis competition in 2006.
"I still love the sport, and I want to see how I feel and play a match I really want to win," he said in January.
"I will catch up with old competitors, old friends, and see if I still have a few things left in the bag," added the 14-time Grand Slam singles winner.
"The stakes are a little bit higher playing in a tournament and against some former greats.
"There's a sense of satisfaction in that. Not like it used to be, but you want to win and play well."
McEnroe and series co-founder Jim Courier also will be in the eight-man field in Boston, where there will be US$142,000 in prize money.
Sampras won seven Wimbledon titles, five US Opens, two Australian Opens, and spent a record 286 weeks ranked world number one.
He is due to be inducted into the International Tennis Hall of Fame in July.
