DELRAY BEACH, United States (AFP) – Australia’s Marinko Matosevic upset US second seed John Isner 6-4, 6-4 Tuesday to reach the second round of the ATP Delray Beach Open.
Isner, who won all three prior meetings with the Bosnian-born Aussie last year, fired 16 aces in a losing cause, surrendering a service break in each set while squandering all three of his own chances in the 75-minute encounter.
Matosevic, ranked 78th and seeking his second ATP final after a 2012 runner-up effort here, booked a second-round date with Japanese qualifier Yoshihito Nishioka, who defeated Dutchman Igor Sijsling 7-5, 6-1. South African top seed Kevin Anderson ousted Aussie John-Patrick Smith 6-3, 6-3 to book a second-round meeting with Taiwan’s Lu Yen-Hsun, who eliminated Aussie Sam Groth 6-7 (6/8), 7-6 (7/5), 6-4.
Two other Aussies advanced, with Bernard Tomic eliminating Tunisia’s Malek Jaziri 6-3, 6-3 and qualifier Thanasi Kokkinakis downing Serbia’s Filip Krajinovic 6-2, 6-3.
Tomic next faces Serbian eighth seed Viktor Troicki, who outlasted France’s Stephane Robert 6-7 (3/7), 7-5, 6-1, while Kokkinakis will meet Croatian fourth seed Ivo Karlovic. US sixth seed Sam Querrey was forced to withdraw with a sore back while leading Colombia’s Alejandro Gonzalez 6-3, 1-2.
