After one day at the U.S. Amateur Championship, Iowa golfers Jed Dirksen and Ian Vandersee are several strokes behind the leader.

Dirksen recorded 13 pars, four bogeys, and one birdie on way to a 3-over 73 in his first round at Blue Mound Golf and Country Club on Monday. All of Dirksen’s bogeys came on par-4s, and he birdied the par-5 18th. The senior finished the day tied for 167th, eight strokes off the lead.

Vandersee fared worse than his Hawkeye teammate. The redshirt freshman shot a 6-over 78 and is tied for 254th. Playing his first round at Erin Hills, Vandersee had four bogeys through his first 14 holes before double-bogeying the par-4 15th. He was able to make a small recovery by posting a birdie on the 16th, but he sits 11 strokes behind the leader after day one.

Two college players are part of a three-way tie atop the leader board. Blake Biddle (UNLV), Gregor Main (UCLA), and John Hahn all fired scores of 5-under par.

Former Hawkeye Vince India is 10 strokes back after posting a 5-over 75 in his first round at Blue Mound.

Stroke play will continue today, and the field will shrink to 64 when match play begins on Wednesday.

Vandersee is set to tee off at 8:10 a.m., Dirksen at 12:55 p.m.
