Robby Ginepri, '05 US Open semifinalist, retires from tennis

Robby Ginepri, a semifinalist at the 2005 U.S. Open, has retired after 14 years on the ATP World Tour.

Ginepri's agency, Octagon, announced his decision Thursday.

The 32-year-old Ginepri's best Grand Slam showing was his run to the final four at Flushing Meadows a decade ago, losing at that stage to Andre Agassi. Ginepri had been the only active American man to reach a Grand Slam semifinal.

Ginepri made it to at least the fourth round at each of the four Grand Slam tournaments and was a member of the U.S. Davis Cup and Olympic teams.

He won three singles titles and reached a career-best ranking of No. 15.
