8:55 p.m. CDT: Imagine being 13 years old and attending the U.S. Amateur Championship. Now imagine that two years later, you're competing in the championship. For Nicholas Cummings, this very scenario is a reality, and, as you'll read, he's anything but intimidated. (Photo: USGA/John Mummert)

7:13 p.m. CDT: USGA officials blew the horn to suspend play due to darkness. Because the suspension was not a result of a dangerous weather situation, players were given the option to finish the hole they were on at the time the horn sounded. Second-round play will resume on Wednesday morning at a time still to be determined. 

6:50 p.m. CDT: Jake Knapp, one of 13 players in the U.S. Amateur field to have competed in the U.S. Open at Chambers Bay, is making a move during Round 2 at Olympia Fields. Playing on the North Course, Knapp holed out for eagle on the par-4 14th hole en route to an outward 30. Knapp, who plays collegiately at UCLA, not only played in the U.S. Open at Chambers Bay, he also won a tournament there last year while competing with the Bruins. Through 27 holes, Knapp is 4-under and in good position to advance to match play. (Photo: USGA/Simon Bruty)

6:15 p.m. CDT: Paul Dunne, who captured the world's attention when he led The Open Championship at St. Andrews through 54 holes, is trending towards locking down a match-play spot at Olympia Fields. The Republic of Ireland native, who attends the University of Alabama-Birmingham, grinded his way to a 1-over 71 on Monday on the North Course, and is off to a good start to Round 2, going out in 2-under 33 on the South Course, putting him at 1-under for 27 holes. 78 players are +3 or better through 27 holes, with 64 players ultimately advancing to match play. Follow score updates here.

4:30 p.m. CDT: A great nine, and great shot, have moved George Cunningham, of Tucson, Ariz., up the leader board at the U.S. Amateur. The University of Arizona sophomore aced the 138-yard par-3 14th hole of the South Course, his fifth hole of Round 2, en route to an outward 30, putting him at 4-under through 27 holes. Cunningham is competing in his first U.S. Amateur, and his strong showing comes at a place where a fellow Arizona Wildcat had the memory of a lifetime. Jim Furyk, who won the 2003 U.S. Open at Olympia Fields, is an alumnus.

3:55 p.m. CDT: A first-time U.S. Amateur participant is making waves at Olympia Fields Country Club. Australia's Maverick Antcliff, 22, carded five birdies on the inward nine of the South Course to power his way to a 5-under 65 and put him safely into match play with a 36-hole score of 3-under 137. With stroke play finished for the week, Antcliff can move on to a format of play that he is very familiar with. "Growing up in Australia, we play a lot of match play. Like if it's for club stuff, state stuff, i've played a lot of match play. It's been a few years, but it's always fun," he said after Tuesday's round.

Antcliff is a student and member of the golf team at Georgia Regents University, which is located in Augusta, Ga., which may give Antcliff some extra motivation for the rest of the week. The winner and runner-up of the U.S. Amateur are likely to get invitations to the Masters. (Photo: USGA/Jeff Haynes)

2:50 p.m. CDT: Steve Irwin struggled to a 6-over 76 on Monday in Round 1 of U.S. Amateur stroke play. He has a five-time USGA champion cheering him on at Olympia Fields on Tuesday, however, in his father, Hale Irwin, who is following the action with his wife, Sally. Hale, a member of the World Golf Hall of Fame, won the U.S. Open in 1974, 1979 and 1990, and the U.S. Senior Open in 1998 and 2000. Steve, who is competing in his second U.S. Amateur, competed in the U.S. Open in 2011. (USGA/Chris Keane)

1:50 p.m. CDT: There is a player with a last name on the top part of the U.S. Amateur leader board that is very familiar in golf circles. Chase Koepka, a rising senior at University of South Florida, is even par through 27 holes, and is currently within the projected match-play cut. Koepka's brother is Brooks Koepka, who won his first PGA Tour event in January and notched top-10 finishes in the last two major championships of 2015. The elder Koepka also tied for fourth in the 2014 U.S. Open at Pinehurst No. 2. Chase has plenty of prowess on the course, as well. He has led USF in scoring average in each of the last two years, and advanced to the Round of 32 in the 2013 U.S. Amateur. Scoring updates can be found here.

1:08 p.m. CDT: One of the hottest players in the world entering the U.S. Amateur was Aaron Wise, of Lake Elsinore, Calif. The 19-year-old rising sophomore at the University of Oregon won the Pacific Coast Amateur on July 31 and almost made it two consecutive wins at the Western Amateur, played about 60 miles up the road from Olympia Fields at Rich Harvest Farms in Sugar Grove, Ill. At the Western, Wise was 1 up through 17 over Dawson Armstrong but the match went to extra holes when Armstrong birdied the par-5 18th hole and Wise settled for a par. On the 20th hole, Armstrong holed a bunker shot for eagle to snatch the victory away. Wise got off to an uneven start yesterday in Round 1 with a 5-over 75 on the South Course, so he'll have to shoot a low round to advance to match play in his second consecutive championship in the Midwest.

12:35 p.m. CDT: Brett Coletta of Australia entered U.S. Amateur week at No. 299 in the World Amateur Golf Rankings. The 19-year-old from Melbourne is making the most of his U.S. Amateur opportunity and is on a roll through 27 holes of stroke play. He followed up a bogey-free 67 on the South Course yesterday by making the turn today at 2 under par, with birdies on the 14th and 16th holes of the North Course. Stay tuned for an update on whether the young Golf Australia team member can keep things going through his final nine holes of stroke play.

12:14 p.m. CDT: With the Walker Cup Match just 25 days away, we caught up with USA Team captain Spider Miller and GB&I captain Nigel Edwards for a video interview that will be posted to usga.org later.

11:40 a.m. CDT: There are 12 competitors in the U.S. Amateur that are USGA champions. Of them, a handful have entered Tuesday play in good position to advance to match play. Among them: 2014 U.S. Amateur champion Scott Harvey, who shot 68 on the South Course on Monday; 2014 U.S. Junior Amateur champion Will Zalatoris, who shot 70 on the North Course, and five-time USGA champion Nathan Smith, who most recently won the 2015 U.S. Amateur Four-Ball Championship with Todd White. Smith carded a 1-over 71 on the South Course on Monday.

11:10 a.m. CDT: An early hot round is in the making from Stewart Hagestad of Newport Beach, Calif. Hagestad, starting on the 10th hole of the South Course at Olympia Fields, carded four birdies against zero bogeys on his first nine en route to an outward 31. Hagestad, who posted a 4-over 74 on the North Course on Monday, played collegiately at the University of Southern California, and is trying to make match play at the U.S. Amateur for the first time in six attempts. Scoring updates can be found here.

10:10 a.m. CDT: One competitor to keep an eye on during Round 2 is Sepp Straka, a rising senior for the University of Georgia. Straka is making just his second appearance in the U.S. Amateur after missing match play in 2012, and posted an opening-round 67 on Olympia Fields' South Course on Monday. He was named co-captain of the Georgia Bulldogs men's golf team for the coming season with fellow U.S. Amateur competitor Lee McCoy, and credits is growing competitive resume as a reason for his recent improvement: "Over the last year, really, I got a lot of playing time at Georgia, and that helped out a lot, just built on my confidence, and here I am."

9:55 a.m. CDT: For the second straight day, the North Course at Olympia Fields will measure 7,216 yards, while the South Course will measure 7,078 yards, so all 312 competitors face the same setup during their respective rounds. During Round 1, the North Course played to a stroke average of 74.506, while the South Course played to an average of 73.295.

9:05 a.m. CDT: Round 2 of U.S. Amateur stroke play got underway at 8:30 a.m. Central Daylight Time after a 90 minute delay to the scheduled start of action, due to inclement weather overnight. All starting times were pushed back 90 minutes. After Round 2 has been completed, the field will be cut to 64 players for the match-play portion of the championship. A playoff will determine the final spots in match play if necessary. A big thanks goes out to the Olympia Fields Country Club grounds and USGA staff members for all their hard work to get the course ready for play. (Photo: USGA/Jeff Haynes)
