New York, United States, 8 September 2013 |

Australia’s Thanasi Kokkinakis has continued his barnstorming run through the boys’ singles draw at the US Open, defeating third seed Christian Garin to reach the final.

A day after ousting second seed Gianluigi Quinzi in the quarterfinals, Kokknakis again came from a set behind to defeat the Chilean 4-6 6-3 6-4 on Saturday in New York.

He will take on No.4 seed Borna Coric of Croatia in the final, who overcame top seed Alexander Zverev 4-6 6-3 6-0 in the other semifinal.

Like in his quarterfinal victory, Kokkinakis’s serve was again the decisive factor; the 17-year-old smacked seven aces while committing no double faults, and won almost 80 per cent of his first serve points, compared with 69 per cent for Garin.

Kokkinakis and Coric have met once previously, with the Australian winning in straight sets in the semifinals of the Australian Open junior event.
