Troy University Player Hannah Toro scored one of the biggest upsets in the 10-year history of the USTA Tennis Classic of Troy on Wednesday.

Toro and her partner, Maci Epstein, a player for the University of Virginia defeated the number two seeds, Maria Abramovic of Croatia and Lenka Wienerova of Slovakia.

The college duo dropped a close first set 6-4 to the professionals, but stormed back to take the second 6-4 on the strength of their returns of serve.

Toro and Epstein then prevailed 10-6 in a match tie break that is used to decide the third and deciding set.

Abramovic is an accomplished doubles player, who has won numerous professional doubles titles including a 25K event in Mexico.

“This win is huge,” boasted Troy University tennis coach, Eric Hayes. “I couldn’t be more proud of Hannah and the way they competed.”

This win will earn Toro a world ranking in doubles, when the new world rankings come out on Monday.

With a mid afternoon start, American No. 5 seed Grace Min took on Rebecca Marino of Canada who is working her way back up the rankings after being out of tennis for about a year.

Min started quickly and relied on footwork that would make her a contender on “Dancing With the Stars.” Marino countered with an aggressive forehand that kept Min off balance.

The first set went to a tie break and Min capitalized on Marino errors to take it 7-5.

Min’s momentum carried into the second set as she grabbed an early break and then held serve the rest of the way to take the second set 6-4.

Min seemed relieved to win her first round against a more experienced and dangerous opponent.

“She hits a big ball and either hits a winner or misses,” Min said of Marino. “Just getting the ball back one more time is key.”

In other matches, second-seeded Edina Gallovits-Hall a Romanian who lives in Atlanta defeated Pila Soumalainen of Finland 6-4, 6-3 and Arina Rodionova of Russia defeated Maria-Fernanda Alvarez-Teran of Bolivia 6-3, 6-1.
