In the first all-American final at the U.S. Clay Court Championships since 2003, Jack Sock defeated Sam Querrey 7-6(9), 7-6(2) for his maiden ATP singles title.

In their first singles meeting, Sock broke his fellow countryman right off the bat for an early 2-1 lead. Querrey responded with an immediate break back, just the second break of Sock’s serve the entire tournament.

On serve at 5-4, rain took the players off the court. Nearly two and a half hour later the clouds parted and play began again.

Holds from both players sent them into a first set tiebreak. Querrey took an early 5-2 lead, but Sock came storming back, saving three set points en route to an 11-9 tiebreak win.

Querrey got his second break of the match in the second set to jump ahead 4-3 but Sock responded with a break of his own to level it up at 4-4. Strong service games from both men pushed them into a second set tiebreak.

The Nebraska native completely dominated the tiebreak rushing to a quick 6-2 lead before serving out the match for his Houston crown.

Sock is the first American to claim his maiden ATP title on clay since Andy Roddick did so by winning Atlanta in 2001. He’s now 19-3 in singles and doubles play for 2015, including one singles title and doubles title, since coming back from a three month hiatus due to injury.

In the ATP Emirates Rankings, Sock is expected to jump up to a career high of World No.36.
