Australian Nathan Green sits just one shot off the pace as the weather caused further chaos on day two of the Canadian Open with heavy rain and lightning bringing an early end to proceedings and preventing any players from completing their second rounds at the Glen Abbey Golf Club in Oakville. Green birdied the first four holes to add to his opening-round 68 to sit on 10-under overall before being halted after 12 holes. He shares second place with Camilo Villegas, who scored 63 in his opening round, Scotland&aposs Martin Laird and American Tim Herron. The Colombian also had three holes to play with three birdies and two bogeys on his card so far. Downpours had also resulted in lengthy delays on the opening day, with several players still needing to complete their first round. That was possible in the early part of today, with Jerry Kelly one of the names to climb the leaderboard. The American fired a seven-under-par 65 to put himself among the leading pack and then went straight back out onto the course to begin his second round. A further five birdies in his second outing helped propel him to top of the standings, with Kelly sitting on 11-under with three holes remaining when play was suspended due to lightning. Laird built on his opening-round 65 with seven birdies and four bogeys in 17 completed holes. Herron was five-under in his second round after 16 holes, with five birdies and no dropped shots. Overnight leader Kim Na was one of a several players yet to begin their second round, along with Scott Verplank, Retief Goosen and Luke Donald. Aaron Baddeley was one of nine players who withdrew during the second round.
