Main fired the lowest 36-hole stroke-play qualifying score in US Amateur championship history with a 10-under-par total for the 36 hole qualification series. A three-time All-American at UCLA, Main shot a bogey-free 5-under-par 67 at the par-72 Erin Hills layout to close out his two rounds. On Monday's opening round he had a share of the first-round lead with a 5-under-par 65 at the par-70 Blue Mound Golf and Country Club.
Blake Biddle, 19, a UNLV player, was two strokes behind Main at 8-under-par to qualify for the elimination match play series as the second seed.
A rain delay of nearly four hours Tuesday forced the second round of qualifying to be completed Wednesday with only a handful of opening-round match play matches completed.
When play was suspended due to darkness, Main was still optimistic regarding his chances despite being 2-down after nine in his match against Bobby Leopold.
"I can take a lot of confidence into match play and hopefully take down my opponents one by one," remarked Main.
Earlier this summer, Main, 22, announced he would not return to UCLA for his senior season and planes to turn professional after theses championships.
Should he win that might change his plans with automatic starts at the US Open, British Open and an invitation to the Masters provided the winner remains an amateur.
"It'd be tough to turn down those exemptions," said Main.
"There's plenty of golf yet to be played and I'll be taking each match as it comes and not thinking about what might eventuate. I need to advance first before that comes into consideration."
Sixty-four players advanced to the match-play portion of the championship, and the cut fell at even par, the cut mark lowered by the easier Blue Mound layout, which according to the USGA played about four strokes easier than Erin Hills over the first two days.
Sixteen-year-old Beau Hossler and collegiate players Blayne Barber, Ben Geyer and 2011 USA Walker Cup player Russell Henley, shot 7-under-par to finish one stroke behind Biddle. USA Walker Cup selection Patrick Rodgers followed at 4-under-par
Defending champion and 2009 and 2011 USA Walker Cup Team member Peter Uihlein, 21, easily advanced to match play at 5-under 137.
All but one of the seven current USA Walker Cup players advanced to match play including Chris Williams at 3-under-par, Harris English and Patrick Cantlay at 2 under-par. Great Britain and Ireland's Walker Cup Team had three of four players advance with world number 2 Tom Lewis, Jack Senior and Michael Stewart all qualifying for the match play.
The Australian contingent competing saw Daniel Nisbet the only Aussie progressing to the match play, with Matt Stieger narrowly missing out after finishing at even with rounds of 69-73 and missing the final match play spot in a three hole play off.
Ryan McCarthy finished at 4-over-par with rounds of 72-74 and Bryden Macpherson at 6-over-par after rounds of 76-72.
Nisbet is unlikely to progress past the first round finding himself behind in his match against Canadian, Mitch Sutton, two down with three to play when all matches were suspended on Wednesday due to darkness.
