London - Milos Raonic was back in the old routine as last year's Wimbledon runner-up advanced to the second round with a 7-6 (7/5), 6-2, 7-6 (7/4) win against Jan-Lennard Struff on Tuesday.
Big-serving Raonic became the first Canadian man to make a Grand Slam final with his impressive Wimbledon run 12 months ago before losing the title match to Andy Murray.
The sixth seed made a business-like start to his bid to make a second major final, in the process extended German world number 53 Struff's losing streak at Grand Slams to 10 matches.
Raonic, 26, will take on Russia's Mikhail Youzhny for a place in the last 32.
