Top seed Isner upset at Memphis tennis

MEMPHIS: Top seeded American John Isner was sent crashing out of the ATP and WTA Memphis Open after losing to Austrian Jurgen Melzer 6-3, 7-6 (8/6) in a quarter-final match Friday.

Isner, who hammered 48 aces in his first two matches in Memphis, fired 11 aces against Melzer in the 81 minute match at the $1.1 million indoor hardcourt tournament at The Racquet Club of Memphis.

Isner also had two double faults and won just 67 percent of his first-serve points.

Melzer won 80 percent of his first-serve points, had seven aces and saved both of his break point chances.

Third seeded Czech Radek Stepanek also cruised into the semis surviving a first-set tie break then dominating the second set to beat Sam Querrey 7-6 (7/5), 6-0.

Stepanek, who finished second here three years ago, posted four service breaks, compared to just one service break for the wild card and 2010 Memphis champ Querrey. (AFP)
