Milos Raonic is guaranteed of being seeded at the second Grand Slam of the year.

The Canadian tennis sensation moved up to 28th in the world rankings Monday, meaning he will be among the seeded players for the French Open in Paris next month. Thirty-two players are seeded at the tournament, which starts May 17.

Raonic, a 20-year-old from Thornhill, Ont., has jumped 128 spots in the rankings since the start of the year. He was ranked 156th at the end of 2010.

Fifteenth-seeded Raonic will face Radek Stepanek of the Czech Republic in the first round of the Barcelona Open Tuesday. Last week he was ousted by Spain's David Ferrer in the third round of the Monte Carlo Masters in Monaco.

In doubles play Tuesday, Raonic and Nicolas Almagro of Spain lost 6-2, 6-4 to Xavier Malise of Belgium and Alexandr Dolgopolov of Ukraine in the first round.
