Eight-time Grand Slam champion Andre Agassi will return to action in July, playing two matches for the Philadelphia Freedoms of World TeamTennis, the 10-team league announced on Thursday.
Agassi, who won 60 career singles titles, played in the league in 2002 and 2004 and will return July 10 against Boston at Philadelphia and play July 17 at Newport Beach.
"Playing World TeamTennis is a great experience," Agassi said. "Team play is a terrific way to showcase tennis. WTT is competitive, it's fun and there's a really great energy from the fans."
Each team plays one set of men's singles and doubles, women's singles and doubles and mixed doubles in matches during a season that runs from July 2-26.
Australian Open champion Serena Williams will play four times for Washington. Venus Williams plays three times for Philadelphia, but never alongside Agassi or against her sister.
Other famous names taking part include Martina Navratilova, John McEnroe, Michael Chang and Anna Kournikova.
