Raonic breezed through the first round, crushing Italian lucky loser Lorenzo Giustino in straight sets in a match held over two days. Rain postponed play Monday with Raonic one game away from winning his first match since October.

The second-round match pitted Raonic, ranked 35th in the world, against the player directly below him in the rankings.
