Nightfall on Saturday found three players tied for the lead at 12-under-par, a walrus lurking just a shot back, a famous shark-hunter within two, and a group of 11 golfers within five strokes of the pace.
Steve Flesch, Chris Riley and Jonathan Kaye all sit atop the leaderboard shooting a 2-under, 5-under, and 3-under respectively.
Bob Tway, who is still best known for holing a bunker shot to defeat Greg Norman at the 1986 PGA Championship, posted a 2-under 70 to remain in the mix at 10-under.
Two of the second round leaders, Ben Crane and Tom Pernice Jr., both shot 1-over-par 73s to drop back three strokes off the pace.
Riley, who quietly had a third place finish at last week's PGA Championship, was making alot of noise early on Saturday. Through five holes Riley was 5-under, birdieing each hole and shooting to the top of the leaderboard. He also recorded three more birdies on the round but gave up three bogeys also.
'It's definitely different on Sunday out there, but the more I get there, the more prepared I feel,' the 28-year-old Las Vegas resident said.
Flesch, coming off a red hot 64 on Friday, shot a ho-hum 70 that kept him in a tie for the lead.
'I hung in there and gave myself a chance for tomorrow. I'm going to go out and play aggressively,' he said.
Kaye, just a shot off the pace coming into the round, made three birdies and posted no bogeys for a 69 and a chance to be in the final group on Sunday.
'We're all pretty hungry so it should be interesting to watch,' said Kaye, the 32-year-old Colorado native who finished second in the Greater Hartford Open and has three top-10 finishes this year.
Stadler, looking for his 13th career victory, had a remarkable round that could have been even better if not for a double bogey on the par-3 16th. He birdied half the holes he played on Saturday, four on the front nine and five on the back side.
'It's been a long time. It's been six years. It might be tomorrow or it might be two years. I'm just going to go out and have a good time,' Stadler said.
Duffy Waldorf, who has finished in the top-10 the last two years in Reno, is four back at 8-under-par.
