Amanda Rothrock put together an even-par back nine Sunday as she held her round together and cruised to the win at the Baton Rouge Women’s Amateur golf championship.

Rothrock began her day on shaky ground. A financial advisor, she bogeyed three of the first five holes before shooting 3-over par 39 on the front nine at Webb Memorial golf course.

On the back side, Rothrock used birdies at holes 12 and 17 to offset bogeys at 10 and 18. She went on to shoot 75 and, coupled with Saturday’s round of 80, earned titlist honors at 11-over 155.

Victoria Hugghins was second at 181. Sharon Madden began the day in second but faded in the heat, dropping seven shots on her final two holes. Madden was third at 183.

For Rothrock, who plays various tournament hosted by the LWGA and the University Club, the win was a welcome surprise.

“I came out here to have fun. I had no real expectations,” said Rothrock, whose usual golfing group was out of town.

“Since everyone was out of town, I decided to come out and play. I made some new friends and saw a lot of (old friends).”

Rothrock hit 11 greens and was on the fringe of three others. She completely missed four greens, leading to bogey each time. She also three-putted No. 10 for a bogey, her only regret of the day.

“I was happy with the way I played,” Rothrock said. “Yesterday I had three 3-putts, and today I had just one. I was pleased and a little surprised.”

Madden, who has qualified for the 2015 Executive Women’s Golf Association Championship at Rancho Mirage, California, turned in the shot of the day when she got up and down from under a tree on 16. She tapped in after playing a low punch into the side of the green that lost its pace and finished inches from the cup.

“I can pitch the ball pretty well on occasion,” Madden said. “I don’t have those shots in my bag every time I play, but I do know they’re in there.”

Tracy Simoneaux of Zachary turned in the second-best round of the day winning the mid-amateur division with a 76. Her two-day total of 158 edged Ginger Covington, who carded a 79 to finish at 160.

The third hole, a short but tight par-3 with out of bounds down the left side, proved to be a nuisance for Simoneaux in both tournament rounds.

“After I got past the first couple of holes, I did OK,” said Simoneaux, a former standout at Southern. “Both days I hit out of bounds on the third hole. Once I got that behind me, I was able to settle down and finish the round.”

Baton Rouge’s Suzanne Seefield took top honors in the senior division. She followed up a round of 84 with an 81 on Sunday for a total of 165. Pat Morgan (183) and Thelma Price (185) were the closest pursuers.

“I started off poorly (Saturday), but then I shot a 38 on the back nine,” said Seefield, who was 10-over through her first nine holes. “I don’t think I’ve ever played that well out here.”

Zachary’s Kylie O’Brien, a 13-year-old student at Northwestern Middle School, came in with tournament experience but found the going tough at first.

“It was definitely different for me because I usually play against girls my own age,” O’Brien said. “This time, I was the youngest competitor, and the closest in age to me was 21.”

O’Brien finished fourth in the championship division at 188.
