John Senden and Steven Allan are the best placed Australians at the Canadian Open and trail progressive leader Chez Reavie by eight strokes during the suspended second round. Senden registered an even-par 71 to be five-under at the halfway point of the tournament and in a share of 21st spot while Allan had one hole left in his round to play before darkness brought about an abrupt end to the day. After recording an opening-round 68, Allan is currently two-under-par after 17 holes in round two leaving him with a progressive total of five-under. However, Reavie created a little breathing room for himself on what was a crowded leaderboard. Reavie surged into first place with a seven-under-par 64 second round, taking a two-shot lead over Eric Axley, who had one hole left to play when play was called for the day. Carding six birdies and an eagle at the par-five 13th, Reavie moved to 13-under 129 for the tournament. The 26-year-old was part of a seven-way tie for first place after the first round, which was completed earlier in the day due to torrential rain that postponed play for nearly six hours on the first day. More than 60 players will return to finish their second round Saturday at 7:30 am local time. The third round will begin three hours later. Reavie is seeking his first PGA Tour title. The Kansas native has just one top-five finish in his brief career, which came at the Bob Hope Classic in January. Axley is the nearest contender at 11-under following his bogey-free round that featured five birdies. His playing partner, Nicholas Thompson, also was five-under for the round and alone at nine-under with just one hole to play. Billy Mayfair (66) and Steve Marino (67) each managed to complete their rounds and are tied at eight-under 134. Cliff Kresege (66), Carlos Franco (68), Ken Duke (67) and Kevin Na (66) all finished at 135. Local favourite Mike Weir was tied for the lead after the first round but was at even-par through 16 holes in his second round and six-under overall thanks to a double-bogey at No.9. The 38-year-old is making his first PGA Tour appearance in Canada since last year&aposs President&aposs Cup, when he defeated Tiger Woods in match play. The lefthander has just two top-10 finishes in 17 starts this season and has missed five cuts. Two-time defending champion Jim Furyk, who finished in a tie for fifth at the British Open last week, carded a three-under 68 and is nine strokes back at four-under 138. Aussies Jason Day and Nick Flanagan are 11 shots adrift of the lead on two-under.
