QUEENS, New York — Alexa Guarachi wasn’t content with simply advancing to the second round of a Grand Slam.
Nah, as witnessed from Saturday’s straight-sets win in Flushing Meadows, the Miramar Beach native has bigger plans.
Guarachi and Bernarda Pera fought off a set point in the first set and beat fifth-seeded Ann-Lena Gronefeld and Demi Schuurs 7-6 (3), 6-2 to advance to the Round of 16 at the U.S. Open.
Schuurs is ranked eighth in the world. Gronefeld is No. 14.
Down they went in straight sets by the 85th-ranked Guarachi and a singles specialist in Pera, ranked 823 in doubles and 65 in singles.
Guarachi and Pera, unseeded, led 5-3 in the opening set before losing three straight games and falling behind 30-40 on serve. But the pair fought off set point, forced a tiebreaker and won the first four points and six of the first seven en route to a 7-3 win.
From there they never looked back, adding three more breaks as they finished 6-for-12 on break-point opportunities.
Now the duo advance to face unseeded Caroline Dolehide and Vania King Sunday at a time to be determined for a quarterfinal bid.
Dolehide is ranked 114 in doubles and King is 198.
