The 23-year-old carded his third 63 of the week to set a tournament scoring record, and a rookie record for the lowest 72-hole total in PGA Tour history.
Finishing 24-under-par, Henley birdied the final five to finish seven under for the round and three shots clear of Tim Clark in second place to ensure his PGA Tour card for the next year as well as spots at the Masters and PGA Championship.
Henley was dominant from start to finish at Waialae, where he played the par fours in 17-under and at one point went 50 holes without a bogey.
Waites bags BDO title
DARTS: Scott Waites cruised to his first BDO World Championship title after beating Tony O'Shea 7-1 in a one-sided final.
Waites was ruthless as he raced to a 5-0 lead, taking 10 legs in a row at one point as O'Shea almost folded completely in his third final.
O'Shea won the sixth set to ensure there would be no whitewash, but any hopes of a comeback were quickly dismissed with Waites claiming the next, and although there was a hint the third seed was feeling the pressure, he managed to hold his nerve.
