NEW YORK - A Blue Valley North graduate is putting on a show at the U.S. Open tennis tournament.
Jack Sock became the first American to advance to the third round of the U.S. Open. The 19-year-old Sock knocked off 88th-ranked Flavio Cipolla of Italy on Thursday, 6-2, 6-2, 6-4 to make the third round of a major for the first time in his career.
Sock is a wild-card entry and the 248th ranked player. He next faces No. 11 Nicolas Almagro of Spain.
Using a powerful serve that clocked between 130-140 mph, Sock dominated Cipolla. The third set didn't prove as easy for Sock. He also had to overcome a distraction. Right before the final game, an ill spectator caused a delay.
Down 40-15 in the final game, Sock fought his way back. On his second match point opportunity, he sealed the deal. Sock pumped his first in celebration.
Sock was born in Lincoln, Neb. but moved to Overland Park when he was in the fourth grade. He went 80-0 at Blue Valley North and captured four state titles.
Singles isn't the only event for Sock at the U.S. Open. He's also playing in men's doubles. Plus, he's looking to defend his U.S. Open mixed doubles title.
