The 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.
The 2010 champion and world No.14 won both sets in tiebreaks, triumphing 7-6 7-6 to end Lu's bid for a maiden ATP World Tour title - and a first-ever too for Taiwan.
Isner served 23 aces as his massive serve proved too much for the plucky Taiwanese - he won 87 percent of points on his first serve.
