Croat Ivan Dodig upset eighth-seeded Aussie round action at the $1.155 million Regions Morgan Keegan Championships.

Dodig blasted 19 aces and came from behind to stop the rising Tomic 5-7, 6-4, 7-6 (10-8) on the indoor hardcourts at The Racquet Club of Memphis.

The top seeds in Memphis are 6-foot-9 American John Isner, former world No. 1 American Andy Roddick, Czech Radek Stepanek and last week's San Jose winner Milos Raonic of Canada. Roddick beat Raonic in last year's Memphis finale to capture the title here for a third time.

The 2012 Memphis champ will pocket $277,915.
