Irving, TX (SportsNetwork.com) - Inbee Park fired a 6-under 65 in Sunday's final round and she went on to win the North Texas Shootout for the second time, this time by three shots.

Park, who now has 14 career victories on the LPGA Tour, finished the week at 15-under-par 269. She also won the inaugural event in 2013.

"I played really solid, the ball-striking was solid, I putted really good all week this week," Park said. "It's been the best I've putted this season. I'm really excited my putting is back. I got a new putter this week and it seems like it's working, so it's going to be in the bag for a long time."

Hee Young Park and Cristie Kerr carded matching 5-under 66s as they tied for second at 12-under 272.

Lexi Thompson, who shared the third-round lead with Inbee Park, shot a 2-under 69 and tied for fourth at minus-11 with Maria McBride (66) at Las Colinas Country Club.

Angela Stanford (69) ended alone in sixth at 10-under 274. Last year's winner Stacy Lewis (67) finished in a tie for seventh at minus-9 with Juli Inkster (67) and Karrie Webb (70).

Tied with Thompson heading into the day, Inbee quickly separated herself and gained the outright advantage with a 20-foot birdie putt at the second. She got up and down from a bunker for birdie at the par-5 third to move to 11- under and remained a shot up.

While Inbee was in the middle of making five straight pars from No. 4, Hee Young and Thompson were both able to tie the lead before the world No. 2 took the outright advantage back once again with a birdie on nine.

Inbee never looked back as she later took a 2-shot lead when she tapped in for birdie at 12. A 10-foot birdie putt dropped at No. 15 for Inbee and gave her a 3-shot advantage.

Hee Young brought it back within two late, but she ran out of holes and ended at 12-under. Inbee parred 16 and 17 before hitting her third shot at the par-5 last to three feet. She kicked that in for a closing birdie and a 3-shot victory.

"I knew I was like two shots ahead going into the last, but you just don't know what's going to happen with what happened to me in Hawaii," said Inbee, who lost in a playoff to Sei Young Kim at the LOTTE Championship in Hawaii two weeks ago. "I really tried to play hard until the end and it was a really good day out there today for me."

Hee Young began her ascent up the leaderboard with an eagle at the par-5 third, getting her to 9-under and tying her for the lead early on. She remained within striking distance with a gain at eight and the 27-year-old tied the lead with her second birdie in three holes at 10.

With Inbee stretching her lead, Hee Young dropped back further with a bogey on 16 before finishing birdie-birdie to pull within two at the time.

Thompson was the last player who had a chance at catching Inbee. A birdie on three kept the 20-year-old within one and another gain on nine briefly tied her for the lead.

Thompson was up and down throughout the back nine. Bogeys on 12 and 15 were paired with birdies on 14 and 16 to keep her at minus-11. Thompson missed a short birdie on 17 that would have pulled her within two at the time and instead she finished par-par to end four shots back.

Kerr made seven birdies and two bogeys, including three straight closing birdies to finish three shots back.

NOTES: Inbee Park missed out on tying Lewis' tournament record of 268 by one shot. Lewis set that mark last year ... Park has now won twice this season. She also won the HSBC Women's Champions in early March ... Park missed just one green all day as she missed the 16th by a couple yards ... The top-10 finishers this week have a combined 131 victories on tour ... Park earned $195,000 with this victory ... The LPGA Tour heads to Virginia in two weeks for the Kingsmill Championship, where Lizette Salas earned her first win by four shots last year.
