OAKVILLE, Ontario (REUTERS) - American Kevin Tway had a late wobble but still took the second-round clubhouse lead at the Canadian Open on Friday (July 27) as overnight pacesetter Robert Garrigus mounted an early charge looking to reclaim top spot.

Tway, son of 1986 PGA Championship winner Bob Tway, had his only bogey at the 17th to drop into a tie for the lead but grabbed top spot all for himself after wrapping up his round with a par for a seven-under 65 and a midway 13-under total.

That effort was enough to leave him one shot clear of South Korea's Kim Whee, with an error-free 65, and American Keegan Bradley, who had the early round of the day carding a nine-under 63 that featured a birdie, eagle, birdie, eagle finish.

Garrigus, who had a one shot overnight advantage, blasted out of the starting blocks with birdies on his opening two holes before picking up his first bogey of the tournament at the par three 12th to sit two behind the leaders with 14 to play.

It was a long day for 55 players who had an early start, returning to Glen Abbey to complete their rain-interrupted opening rounds.

Venezuela's Jhonattan Vegas, bidding to become the first to win three consecutive Canadian Opens, looked poised to make a move until bogeys on two of his last three holes saw him settle for a two-under 70, eight off the pace going into the weekend.

Sergio Garcia got his day off to promising start with a birdie on his opening hole but the 2017 Masters champion could not get anything going, returning a two-over 74 that left the Spaniard right on the projected three-under cut line.

US Open champion Brooks Koepka had a two-under 70 but it was not enough to undo the damage of a disastrous opening round 77, with the big-hitting American on three-over and packing his bags for an early exit.
