Sunday's pro golf roundup

C.T. Pan took advantage of top-ranked Dustin Johnson's back-nine meltdown Sunday to win the RBC Heritage in Hilton Head Island, S.C., for his first PGA Tour victory.

Along with winning $1.242 million, the 27-year-old Taiwanese player became exempt on tour through 2020-21, moved in line to make the President's Cup International team this year and will have an opportunity he's dreamed about since taking up the game in the mid-1990s — playing at Augusta National.

"It's still really hard for me to believe," he said. "I'm processing. … I'm so happy I finally got it done."

Pan shot a 4-under 67 to finish at 12-under 272, a stroke ahead of Matt Kuchar and two in front of Patrick Cantlay, Scott Piercy and Shane Lowry. Kuchar had a 67, Cantlay and Piercy had 69s and Lowry a 70.

The top-ranked Johnson, the third-round leader in his home-state event, shot a 77 and tied for 28th at 4 under. He played a five-hole stretch in 7 over, making bogeys on Nos. 11-13 and double bogeys on Nos. 14-15.

Brooke Henderson successfully defended her title in the Lotte Championship on Saturday in Kapolei, Hawaii, and tied Sandra Post's record for LPGA Tour victories by a Canadian with eight.

Henderson, 21, closed with a 2-under 70 for a four-stroke victory over Eun-Hee Ji.

Nelly Korda, tied with Henderson for the third-round lead, finished with a quadruple-bogey 8 for a 77 that left her seven strokes back at 9 under. She hit into the water twice on 18, then threw her ball in after finishing. Korda also had a double bogey on the par-4 seventh.

Scott McCarron completed a wire-to-wire victory in the Mitsubishi Electric Classic in Duluth, Ga. McCarron, 53, closed with a 1-under 72 for a two-stroke victory over Jerry Kelly, Joe Durant, Kirk Triplett and Kent Jones.
