Those four tennis greats — owners of a combined 37 Grand Slam titles — will participate in the 2011 BNP Paribas Showdown exhibition matches at Madison Square Garden on Feb. 28.
Sampras-Agassi will be best of three sets. McEnroe-Lendl will be one set of first to eight games.
Sampras and Agassi met in three U.S. Open finals in New York, with Sampras winning each time, including his first major title in 1990 and his 14th in 2002 — the last match of his career.
McEnroe won the U.S. Open four times, and Lendl three. They met for the title in 1984, with McEnroe winning, and the next year, when Lendl won.
Tickets go on sale Sept. 27.
