'It's very wet. It's very sloppy,' said Lickliter. 'You just have to stay patient You have to not hurry, try and not to rush yourself. Just try to stay focused.'
Inclement weather forced the third and fourth rounds to be completed on Sunday. Everything went as scheduled over the first 18 holes. Lickliter fired a 5-under-par 66 to take a two-shot lead over Dan Forsman (67) at 13-under-par.
Henry came out firing in the afternoon 18, carding four birdies over his first six holes. He added two more at Nos. 10 and 13 to move to 16-under-par.
Lickliter wasnt as spectacular, but was consistent. He birdied the 5th, 6th and 9th holes to maintain his position at the top of the leaderboard.
Final-round play was halted on three occasions. The first stoppage lasted nearly two hours, while the second didnt even warrant players to leave the course. The stop-and-start play stopped for good at 6:42 p.m. ET.
Both Lickliter and Henry are in search of their first PGA Tour title. Lickliter has come close once this season, losing in a bizarre playoff to Phil Mickelson at the Buick Invitational in February.
Mickelson was just two shots off the pace through 36 holes, but carded a disappointing 1-over-par 72 in the third round. The left-hander is 4-under through ten holes of his final round. He is at 10-under-par, six shots off the lead.
Forsman is 2-over through 11 holes. He hit his tee shot out of bounds on the 5th hole just seconds before play was suspended for the first time. He eventually carded a double-bogey 6 and stands at 9-under-par for the tournament.
