Moscow: Top-seeded Milos Raonic of Canada was eliminated in his first match at the Kremlin Cup on Thursday, losing 6-3, 4-6, 6-3 to Lithuanian qualifier Ricardas Berankis.
Raonic had a bye into the second round, and the loss puts him in danger of failing to qualify for next month's ATP tour finals in London.
Playing with his right arm in strapping, the ninth-ranked Canadian struggled with his usually powerful and accurate serve, landing only 59 percent of first serves.
For the 116th-ranked Berankis, it was his first career win against a top-10 player. His reward is a quarterfinal against Spain's Roberto Bautista Agut, seeded fifth.
Earlier Thursday, last year's runner-up Mikhail Kukushkin knocked out fourth-seeded Fabio Fognini of Italy 6-4, 6-2.
