Doubles specialist Martin Damm retires

Czech doubles specialist Martin Damm has retired from

professional tennis.

The 38-year-old Damm told the current issue of the Czech tennis

magazine Tennis Arena he decided to retire after recent poor

results and because of his age.

He said he was not leaving the sport and will coach American

Ryan Harrison.

Damn turned professional in 2000 and won 40 ATP doubles titles.

He teamed up with Leander Paes to win the 2006 U.S. Open and a year

later reached his highest doubles ranking at No. 5.
