ISCO Championship playoff format: Harry Hall wins on third extra hole

8:15 p.m. ET update: England's Harry Hall earns his first TOUR title in dramatic fashion, chipping in for birdie on the third playoff hole, the par-3 ninth, to win the ISCO Championship.

Pierceson Coody and Matt NeSmith cannot hole their shorter birdie chips from just beyond the green, and Hall is a PGA TOUR winner. Hall and his wife Jordan are expecting their first child next week, making the moment all the sweeter.

7:59 p.m. ET update: All three remaining competitors make par on the second playoff hole. They'll head to the par-3 ninth for the third extra hole, looking to determine a winner in a marathon ISCO Championship finish.

Pierceson Coody's tee shot finds the water hazard to the right of the fairway, but he catches a good break with the tides and is able to play the shot; he wedges to 22 feet and two-putts for par. Harry Hall two-putts from 17 feet, and Matt NeSmith has 13 feet to win (his second straight hole with the closest birdie look) but it slides off to the right.

7:45 p.m. ET update: And then there were three. Matt NeSmith, Pierceson Coody and Harry Hall advance to the second playoff hole, again the par-4 18th at Keene Trace, with pars on the first extra hole.

NeSmith has the best chance to win, but his 8-foot birdie try slides off to the right. Coody two-putts for par from 26 feet, while Hall gets up-and-down from a greenside bunker.

Zac Blair and Rico Hoey are eliminated after making bogey on the first extra hole. Both players miss the fairway off the tee, miss the green on approach, and cannot convert mid-range par putts.

The ISCO Championship is headed to a sudden-death playoff.

Matt NeSmith, Zac Blair, Pierceson Coody, Harry Hall and Rico Hoey all carded 22-under 266 at Keene Trace Golf Club outside Lexington, Kentucky, requiring overtime to determine a winner on a chaotic Sunday in the Bluegrass State.

The playoff format is as follows: 18, 18, 9, 18, 9, 18. (Holes 9 and 18 would continue to be played in rotation until a winner is determined.)

The par-4 18th measures 423 yards, with a pond down the hole’s right side and bunkers down the left. The par-3 ninth measures 209 yards, played across a water hazard.
