Amateur Wenyi Ding, number 4 in the world, has withdrawn from the US Amateurs.

Ding, a rising sophomore at Arizona State, was originally scheduled to play the two rounds of stroke play qualifying alongside fellow Sun Devils Preston Summerhays and Ben James of Virginia, but has since been removed from the teeing list.

The USGA said Ding’s withdrawal was due to an “injury” but could not provide details.

Ding has played little this summer, but won the Southern Amateur before finishing 67th in the Western Amateur. He was coming off his debut spring semester in which he posted five top-six finishes, including a win at the Amer Ari Invitational in February.

Ding is also number 1 in the Global Amateur Pathway Rankinga new ranking that rewards the top non-college amateur each year with a DP World Tour card. Ding’s inclusion in the ranking has naturally sparked speculation about his future plans. According to the program’s website, to be eligible for the ranking, a player “must not be a current NCAA Division I player” and “be at least 20 years old at the end of the calendar year.” Ding, who turns 20 in November, has not announced any intention to turn pro and remains on Arizona State’s 2024-25 roster.

The first ranking period ends on October 13. The top player will receive DP World Tour status for the 2025 season. Ding is nearly 1.4 average points ahead of former Arkansas player Jacob Skov Olesen. That’s about the same gap between Olesen and Nathan Petronzio, a Texas native who is ranked No. 6.

The U.S. Amateur field for next week’s championship in Hazeltine includes the other nine top-10 amateurs in the world, including No. 1 Gordon Sargent, No. 2 Jackson Koivun and No. 3 Luke Clanton, who are grouped together for stroke play.

Clanton’s status, however, remains uncertain as the Florida State junior competes in the PGA Tour’s Wyndham Championship. Clanton shot 2-under par in the first round, putting him inside the cut line, but due to extreme rainfall from Hurricane Debby, he was not scheduled to begin his second round until 4:01 p.m. ET on Saturday. Clanton’s group tees off at 2:09 p.m. CT on Monday at Chaska Town Golf Course.

A request sent to Clanton’s agent on Friday about Clanton’s plans in the event Clanton makes the cut and Wyndham advances to Monday went unanswered.
