Tokyo - Top-seeded Juan Martin del Potro moved into Japan Open quarter-finals with a comfortable 6-2, 6-2 win on Wednesday of fellow Argentine Carlos Berlocq.
Del Potro broke Berlocq's serve twice in the second set and closed out the match in 1 hour, 6 minutes.
Del Potro was a late addition to the tournament after Andy Murray, the 2011 champion, withdrew due to a back injury. Del Potro is seeking his third title of the season here, following victories in Rotterdam and Washington.
In other matches, third-seeded Milos Raonic of Canada advanced to the second round with a 6-4, 7-6 (0) win over Go Soeda of Japan.
Raonic, coming off a win at the Thailand Open on Sunday, dominated Soeda with his serve, hitting 24 aces against the Japanese wildcard.
