SAN FRANCISCO — A grueling Thursday at The Olympic Club has come to a close, and the 2025 U.S. Amateur is down to eight golfers vying for the Havemeyer Trophy.

After Thursday morning's Round of 32, winners were back on the course in the afternoon battling in the Round of 16, and eight golfers punched their ticket into the quarterfinals, which begin Friday afternoon.

Among those advancing to the quarterfinals include a local favorite with incredible crowd support, John Daly II and a Cinderella story in the making.

Here's a look at the eight quarterfinalists in the U.S. Amateur at Olympic Club, as well as Friday matchups and TV information.

Shiels Donegan, the North Carolina transfer who lives about an hour north of Olympic Club, took out medalist Preston Stout 1 up on Thursday afternoon to move into the quarterfinals. He also has the biggest crowd support this week.

No. 56 Jacob Modleski

Jacob Modleski plays his tee shot on the 11th hole during the round of 16 of the 2025 U.S. Amateur at The Olympic Club (Lake Course) in San Francisco, Calif. on Thursday, Aug. 14, 2025.

Modleski, who was on the bubble for the U.S. Walker Cup team coming into the week, is into the quarters after holding off Paul Chang 2 up. In the 18 holes the two played, they only tied two of them.

No. 61 Jimmy Abdo

No. 26 John Daly II

Miles Russell reacts after sinking his putt on the 17th hole to win his match during the round of 16 of the 2025 U.S. Amateur at The Olympic Club (Lake Course) in San Francisco, Calif. on Thursday, Aug. 14, 2025.

The top-ranked junior in the world is into the quarterfinals at his second USGA event this year. Russell, 16, tops Mahanth Chirravuri 2 and 1 after burying a long birdie putt on the 17th hole to win.

No. 3 Eric Lee

Eric Lee plays a shot from a bunker on the third hole during the round of 16 of the 2025 U.S. Amateur at The Olympic Club (Lake Course) in San Francisco, Calif. on Thursday, Aug. 14, 2025.
