Paris: Nick Kyrgios has rounded out his very limited French Open preparation with a breakthrough doubles triumph in Lyon.

Kyrgios, who faces fellow Australian Bernard Tomic in a marquee first-round match up in Paris on Monday, teamed with American Jack Sock to land his maiden ATP doubles crown in Lyon.

Kyrgios and Sock edged out Czech Roman Jebavy and Dutchman Matwe Middelkoop 7-5 2-6 11-9 in a deciding match tiebreak on Saturday.

The Australian No.1 is seeded 21st for the Roland Garros grand slam but remains under a fitness cloud having not played singles in six weeks due to an elbow injury.

Should he take his place in the French Open draw, Kyrgios and Tomic will square off for the first time.

Tomic is riding a seven-match claycourt winning streak after successfully qualifying in Paris with three impressive straight-set wins.
