Savannah, GA, USA, 28 April 2014 |

Nick Kyrgios has won his second ATP Challenger title in as many weeks with a come-from-behind victory over Jack Sock in the final of the Savannah Challenger in Georgia.

Celebrating his 19th birthday in style, Kyrgios triumphed 2-6 7-6(4) 6-4 over the American Sock to win the third Challenger-level title of his burgeoning career.

It was his second straight tournament victory on American green clay following his triumph at the Sarasota Challenger in Florida the previous week, and takes his winning streak to 10 matches.

Despite picking up a minor injury during the final in Savannah, the win is expected to boost his ranking to about 150, a career-high mark.

“Awesome couple of weeks, nice rewards for the whole team and our hard work. Couldn’t have asked for much more. Nice Bday pressie too!!” he tweeted.

“I have a slight abductor strain which is painful but I hope to be okay for Tallahassee next week so I can keep this run going.”

Kyrgios had earlier cruised into the final following four consecutive straight-set victories, including a 6-1 6-3 win over fellow Aussie young gun and good friend Thanasi Kokkinakis.

He dropped no more than seven games in any of those matches, a dominant performance preceding his gutsy triumph in the final.
