Ivan Lendl is going to sub for Jimmy Connors on four stops in the upcoming series of matches around the country featuring several former Grand Slam champions.
Andre Agassi, John McEnroe and Pete Sampras also are in the group of competitors scheduled to take part in the four-player mini-tournaments. Each event will feature one-set semifinals and a one-set title match.
Connors is out with a hip injury, so Lendl is planning to compete in Chicago, Detroit, Boston and San Jose, Calif. Michael Chang will fill in when the series comes to Surprise, Arizona, Tampa, Florida, and Atlanta.
Formerly known as the Champions Series, the PowerShares Series begins Oct. 13 in Surprise, and the final day is Nov. 30 in Anaheim, California.
Lendl, who won eight major titles, coached Andy Murray to this year's U.S. Open championship.
