MONTREAL — Frederic Niemeyer officially retired from professional tennis during a news conference Thursday, but he won't be leaving tennis altogether.

Niemeyer instead will join Tennis Canada as a personal coach for promising 18-year-old Milos Raonic of Thornhill, Ont. Niemeyer will train Raonic in Montreal and also will travel with the teenager 18 weeks a year on the pro tour.

Raonic made his ATP Tour debut at this year's Rogers Cup in Montreal, winning his first two matches against No. 77 Teimuraz Gabashvili of Russia and No. 113 Michael Llorda of France to advance through the qualifying. He then delighted an overflow crowd at the BN grandstand court, taking 11th-seeded Fernando Gonzalez to the limit before losing 4-6, 7-6 (6), 6-4.
