Riley holds first-round lead at U.S. Junior Amateur

The Woodlands, TX ( - Davis Riley fired a 5-under 67 on Monday and he holds the outright lead after the opening round of stroke play at the U.S. Junior Amateur Championship.

Riley is playing in his third U.S. Junior Amateur Championship, where he finished runner-up to Scottie Scheffler at Martis Camp Club last year. Riley also won the Terra Cotta Invitational in April.

The 17-year-old holds a 1-shot lead over Joshua Sedeno and Sam Horsfield on the Nicklaus Course at The Club at Carlton Woods. Both Sedeno and Horsfield are at 4-under 68.

Horsfield, who is also making his third appearance at this event, was ousted in the round of 32 at last week's U.S. Amateur Public Links.

Jacob Solomon, Cheng Jin, Braden Thornberry, Tony Gil, Brad Dalke, Thomas Longbella and John Mancinotti are all two shots back of the lead at 3-under 69.

Riley had a strong, bogey-free day that also saw him card five birdies. After beginning his round with a par, Riley quickly got into red numbers with a birdie at the par-4 second hole. He added another par at three before pouring in his second birdie at four.

Four-straight pars preceded Riley's third birdie on the front nine at No. 9, and he backed that up with another birdie at No. 10. He added one more gain at No. 14 and made pars on the rest of his back nine holes.

Sedeno had trouble on the front nine with bogeys at four and seven to go along with a birdie at eight. Sedeno finished the front nine at 1-over, but he turned things around on the back nine.

After three straight pars from 10, Sedeno rattled off four straight birdies from No. 13 and he finished out his round with a birdie at 18, putting him in a tie for second at 4-under.

Horsfield started off slow as well with a bogey at the second, but he made up for it with three birdies at three, four and eight. He made back-to-back birdies at 10 and 11 before making five straight pars from 12.

A bogey at 17 had Horsfield at 3-under, but a birdie at the last vaulted him into a tie for second with Sedeno.

The second and final round of stroke play continues on Tuesday, with the top-64 finishers advancing to match play. The match play portion of the championship starts on Wednesday and runs through the 36-hole final on Saturday.
