UPDATE 1-Tennis-Opelka fires 27 aces in beating Nishioka in Florida

Towering American Reilly Opelka beat Japan's Yoshihito Nishioka in three sets to win his second career ATP Tour title at the Delray Beach Open in Florida on Sunday.

The fourth-seeded Opelka clinched victory in style, pounding his 27th ace of the match down the centre line for a 7-5 6-7(4) 6-2 triumph. The American had surprised Canada's second-seeded Milos Raonic 4-6 7-6(6) 6-3 in their rain-delayed semi-final earlier on Sunday to set up the meeting with the rested Nishioka. Nishioka had beaten France's Ugo Humbert 1-6 6-4 6-0 on Saturday before rain washed out other matches at the Florida tournament.

Opelka's only other title came a year ago in the New York Open.
