Kentucky senior-to-be Megan Broderick and Georgia Tech star Irina Falconi upset second-seeded Kimberly Couts and Tetiana Luzhanska 7-6 (5), 2-6 (10-7) to advance to the second round of women’s doubles at the Fifth Third Bank Tennis Championships.

Broderick-Falconi will play Jacqueline Cako and Story Tweedie-Yates on Thursday.

Krista Hardebeck, 15, looked like a veteran at UK’s Hilary J. Boone Tennis Complex, saving four match points against Lindsay Lee-Waters in the second set and then pulling out a tiebreaker in the third, 3-6, 7-5, 7-6 (2). “She was serving for the match 5-3, 40-love when a (questionable) call went against her,” the home-schooled Californian said. “She seemed rattled after that ... and I settled down.”

“I figured she’d know what to expect from me, so I tried not to fall into patterns, and I varied my shot selection,” said the youngster who knew Lee-Waters — now the mother of two — had been ranked as high as No. 43 back in ’96. Hardebeck is gunning for the National 18-Under Hardcourts in August for a wild card into the U.S. Open.

Wednesday’s fallen seeds were No. 2 Ricardas Berankis of Lithuania, who retired with a triceps strain, giving Alex Bogomolov, Jr., a 6-3, 4-3 win; and No. 6 Heidi El Tabakh of Canada, who was never in the 6-2, 6-1 match with former top-ranked Amercian junior Ashley Weinhold.
