Playa del Carmen, Mexico — Russell Knox and Graeme McDowell each had six birdies and were tied for the lead before the final round was stopped Sunday in the rain-delayed OHL Classic at Mayakoba, setting up a sprint to the finish Monday in Mexico.
The fourth round was delayed 3½ hours by thunderstorms that left pools of water across El Camaleon Golf Club.
McDowell elected to finish the par-5 13th when the horn sounded to suspend play because of darkness. He made birdie to join Knox at 19-under par.
Knox was still on the 13th hole.
Jason Bohn, who chipped in for eagle on the fifth hole for an early lead, dropped two shots and was at 17 under through 12 holes. Bohn won his first PGA Tour event in 2005 and his next one in 2010. This is his final event of 2015.
The final round was to resume at 8 a.m. Monday.
This will be the first time in 10 years that back-to-back PGA Tour events finished on Monday because of rain. The Sanderson Farms Championship in Mississippi had a marathon finish last Monday because of the weather.
With soft conditions, there figures to be little room for error when Mayakoba ends on Monday.
Scott Brown (through 14 holes) and Derek Fathauer (12 holes) were four shots behind. Fathauer, trying to make it six straight PGA Tour events with a first-time winner, had a one-shot lead starting the final round but had only one birdie against two bogeys to fall back.
Knox is coming off his first win last week in Shanghai at the HSBC Champions, and he was so exhausted that he considered pulling out this week. Instead, he continued his around-the world journey to Mexico. He can become the first player since Camilo Villegas in 2008 to win his first two PGA Tour titles in successive weeks.
The 30-year-old from Scotland ran off four straight birdies starting at No. 3, and then stuffed his approach just short of the pin on the par-3 eighth and went out in 31. He picked up his sixth birdie on the 11th hole.
McDowell has not had a top 10 since the Dubai Desert Classic in February. He chose to end his European Tour season earlier than usual because of a mediocre season, and because he has never fared well on the course for the DP World Tour Championship in Dubai next week.
Along with his three straight birdies on the front nine was a par on the opening hole at El Camaleon. McDowell had played that hole in 5 over through three rounds — two double bogeys and a bogey. This time, he hit 3-wood off the tee.
PGA Tour rookie Harold Varner III, Justin Leonard, Patrick Rodgers and Freddie Jacobson were at 13 under, six shots behind.
Inbee Park won the Lorena Ochoa Invitational, holding off Carlota Ciganda for her fifth victory of the season and 17th LPGA Tour title.
The second-ranked South Korean star birdied the final two holes for a bogey-free 8-under 64 and a three-stroke victory over Ciganda in cloudy conditions at tree-lined Club de Golf Mexico.
Ciganda shot a 63. The Spaniard eagled the par-5 second hole and had eight birdies and a bogey.
Park finished at 18-under 270. She was making her first start since withdrawing in China two weeks ago because of a cyst on her left middle finger.
Park took the lead from top-ranked Lydia Ko in the Vare Trophy standings for season scoring average and moved within three points of Ko in the player of the year standings. Park earned $200,000 and is second on the money list with $2,570,096.
Ko skipped skipping the tournament to rest for her title defense next week in the season-ending CME Group Tour Championship in Naples, Florida.
Sweden's Kristoffer Broberg won the BMW Masters for his first European Tour title, beating American Patrick Reed with a 10-foot birdie putt on the first hole of a playoff.
Broberg closed with a 5-under 68 to match Reed (67) at 17-under 271 at Lake Malaren.
Sweden's Henrik Stenson (68), South Korea's An Byeong-hun (70), Denmark's Lucas Bjerregaard (70) and Thailand's Thongchai Jaidee (71) finished a stroke back.
The event was the third of four in the European Tour's Finals Series. The DP World Tour Championship is next week in Dubai, United Arab Emirates.
Son of Davis Love III gets sponsor exemption to Sea Island
The son of Davis Love III will make his PGA Tour debut next week at the tournament where his father is the host.
Dru Love — his given name is Davis Love IV — has received a sponsor exemption to the RSM Classic at Sea Island, the final PGA Tour event of the year.
Love plays for Alabama and won the Puerto Rico Classic this year. He also won the Georgia State Amateur Championship on the Seaside Course at Sea Island, the main course for the RSM Classic.
The RSM Classic is being held on two courses at Sea Island this year because the tournament wanted to be sure everyone with full tour status got in. At the commitment deadline Friday, Mark Hensby was first alternate.
