Kim, tied for 26th at 4 under through 15 holes when second-round play was suspended Friday night, went birdie-birdie-eagle Saturday morning for a 2-under 69, then added a bogey-free 64 in the third round to match Reavie at 15 under.
Ive put myself in a good position, said Kim, seeking his third victory of the year. Im looking forward to the challenge tomorrow.
Reavie was 2 under through 16 holes when darkness ended play on the course saturated by more than 8 inches of rain in a week. He had a 25-foot putt from the fringe on No. 17 when he called it a day.
When we got up to 17, I didnt want to putt. It was too dark to read my putt, said Reavie, the 26-year-old former Arizona State player in his first PGA TOUR season. We figured we had to play 18 in the morning, so what difference does finishing 17 do.
Kims morning finish gave him a 7-under 29 on the back nine after he played the front nine Friday in 5-over 40. The 23-year-old American played the final nine holes of the second round and first nine holes of the third in 11-under 60.
He birdied the par-5 18th in fading light to tie Reavie.
It was a pretty long day, Kim said.
Scott McCarron had a 63'the best round of the week'to get to 12 under. He had 11 birdies, three bogeys'all in the first four holes'and four pars.
Steve Marino (67) also was 12 under, and Billy Mayfair (68) followed at 11 under. Marino birdied the final five holes on the front nine.
Canadian star Mike Weir birdied four of the last five holes for 68 to join to Mark Calcavecchia (67), Sean OHair (67) and Nicolas Thompson (70)at 10 under. Two-time defending champion Jim Furyk was 8 under after a 67.
Im happy where Im at, Weir said. This has been tough for everyone.
Because of the wet conditions, players were allowed to use preferred lies in the fairways for the third straight day.
Reavie played 33 holes in 13 under Friday, shooting 65-64 for a tournament-record matching 13-under 129 total and a three-stroke lead after the completion of the suspended second round Saturday morning.
He made a 15-foot birdie putt on No. 10 to take a three-stroke lead over Kim and Marino at 16 under, but had three bogeys, two birdies and a par on his final six holes to drop back to 15 under.
Bands of rain showers moved in soon after the second round finished, flooding bunkers and fairways. Third-round play was suspended because of lightning at 12:44 p.m., and rain kept the players off the course for 2 hours, 40 minutes.
Furyk won in 2006 at Hamilton and 2007 at Angus Glen. Reavie has an apparel deal with Toronto-based Quagmire Golf. The winner will receive $900,000 from the $5 million purse.
