Andre Agassi will retire after this year's U.S. Open, leaving tennis after two decades during which he collected a career Grand Slam and morphed from "Image Is Everything" brashness to elder statesman.

The 36-year-old American announced his plans Saturday during a news conference at the All England Club, where Wimbledon starts Monday.

"It's been a lot of sacrifices the last few months, trying to get myself right to come back here and enjoy this tournament for the last time," said Agassi, who has played only one match during the past three months because of back trouble.

"It's been a long road this year for me, and for a lot of reasons. It's great to be here. This Wimbledon will be my last, and the U.S. Open will be my last tournament."

He intends to play in four hard-court events in the United States between Wimbledon and the Open, in what will amount to a farewell tour for one of the most popular and successful tennis players in history.

"There's still a lot of fight left in me from here through the Open," he said.

Agassi has won eight major singles titles — one each at Wimbledon and the French Open, two at the U.S. Open and four at the Australian Open — and is one of only five men to have collected at least one championship at each of the Grand Slam tournaments.
