American No. 1 John Isner has won his second Heineken Open tennis tournament in Auckland with a straight sets victory in the final over Taiwan's Yen-Hsun Lu.
Isner won both sets in tie-breaks, winning 7-6 7-6 to end Lu's bid for a maiden ATP World Tour title.
Just like his three-tiebreak quarter-final win over the German Philipp Kohlschreiber, the match saw no breaks of serve.
Isner says has peaked at the right time, going into next week's Australian Open.
"I was very happy with how I played apart from all the break points missed I was extremely happy with, with everything really, I felt I was hitting the ball the best I'd hit it all week and that's a very good sign going forward."
John Isner won 87% of points on his first serve in the final - and he served 23 aces.
Earlier, second seeds Julian Knowle of Austria and Brazilian partner Marcelo Melo won the doubles title.
The pair clinched their first title together with a match tie-break, coming back to beat another Austrian-Brazilian combination, the top seeds Alexander Peya and Bruno Soares, 4-6 6-3 10-5 in the final.
The victory over the former Heineken Open champions Peya and Soares is Knowle's 17th ATP doubles title and first with Melo, who's now won 13.
