PENN TWP — Bailey Tardy’s first round left her disappointed.

Her second round more than made up for it.

The Georgia resident shot a two-under-par and tournament-low 69 in the second round of Monday’s U.S. Women’s Open Sectional Qualifier at Butler Country Club.

She topped the 62-golfer field with a total score of 146 to earn one of two berths into the U.S. Women’s Open, scheduled for July 7-10 at CordeValle in California.

Nannette Hill of Pelham Manor, N.Y., grabbed the second spot with a 76-71-147.

Tardy struggled on her first 18 holes, shooting a 77 with seven bogeys against just one birdie.

“This course is super-long,” said Tardy, who recently capped her freshman year at the University of Georgia. “I’m long off the tee, so that was an advantage for me, but I just wasn’t hitting the ball straight today. I knew scores wouldn’t be that low, but I bogeyed No. 18 to end the first round and was pretty down on myself.”

In between rounds, Tardy called her swing coach.

“He told me to focus on hitting good shots like I did to qualify for (the NCAA Championships, to be held in Oregon beginning Friday).”

It was simple advice, but it turned Tardy’s game around. Her three second-round bogeys were outweighed by five birdies. Four of those came in the final seven holes.

Tardy had golfed here before, qualifying for the U.S. Women’s Open in 2014. She got in a practice round on Sunday in poor weather conditions.

“It was cold, snowing, sleeting. It was brutal and I was not in my element. It wasn’t that bad today. It was a lot windier on Sunday.”

Hill is a professional who is in her second year of playing a full LPGA schedule. Her second round was not quite as impressive as Tardy’s, but it got the job done.

After a first round that featured two birdies, five bogeys and one double-bogey, Hill was very consistent in her second 18 holes. She birdied No. 16, a 480-yard par-5, to pull her score for the round to even par and that’s where she remained.

“The difference for me in the second round was I hit more fairways and greens,” said Hill, who qualified for and played in the U.S. Open in 2009 at Saucon Valley Country Club in Bethlehem, Pa., where she did not make the cut. “Anytime you have a putter in your hands, it’s good. Putting is one of the strengths of my game, along with my long irons.”

Hill was one of several golfers who did not play a practice round Sunday.

“The weather conditions were so bad,” said Hill, 29. “We thought it would be better if my caddie and I just walked the course, mapped out the greens.

“This course is really hard,” she added. “A lot of girls were hitting 4- and 5-irons into most of the greens.”

Monday was the first time Hill had ever played BCC’s course, but her LPGA experience helped her advance.

“The LPGA is a grind. Every shot matters and I’m used to playing a lot of golf. It makes you mentally tough,” she said.

Waynesburg’s Rachel Rohanna earned the first alternate spot, carding a 75-75-150. Ana Sanjuan of Bloomington, Ind., is second alternate after a 78-75-153.

Sarver’s Audrey Clawson was one of six golfers who withdrew from the tournament before it began. Eight others dropped out during Monday’s play.
