Rafael Nadal vs. Jesse Levine takes place later today at the Rogers Cup 2013 in Montreal (19:00 BST).
Having observed Nadal in practice last week, he appears to be moving well, with no visible sign of the knee injury which caused him problems at Wimbledon earlier this summer.
The Spaniard's training over the past few weeks has been quite light, and the big question will be how his legs hold up to the punishment they'll take on the cement of North America over the next month, starting this week at the Montreal Masters.
Nadal shouldn't have too many problems against Levine, however. The wildcard knocked out Xavier Malisse 6-4 7-6 in the first round, and although he has a smooth game with his lefty serve and fluent forehand, it's hard to see him having the power to really trouble the world No. 4.
Levine has never made the third round of a Masters 1000 tournament before, while Nadal is a two-time Rogers Cup champion, having won the tournament in 2005 and 2008. This tournament has been less of a happy hunting ground for him over the past few years though. He suffered a shock second round defeat to Ivan Dodig two years ago and in 2010 he was soundly out played by Andy Murray in the semi-finals.
If Nadal wins he will probably face Wimbledon semi-finalist Jerzy Janowicz in the third round - a fascinating prospect as Janowicz really relishes playing the big names. It would almost certainly be a night session match which Janowicz would relish and his brute power could give the Spaniard some difficulties.
