Russian top seed Dmitry Tursunov was stunned by Canada's Frank Dancevic Friday in the quarterfinals of the ATP Indianapolis Open.

Tursunov was sent packing 6-3, 6-7 (5-7), 6-2 in the hardcourt tennis event while Dancevic, snapping a run of three-straight losses to Tursunov, set up a semifinal clash with third seed Sam Querrey, a winner over French number seven Marc Gicquel 6-4, 7-5.

Two all-American quarterfinals took place at the bottom of the draw.

2005 champion Robby Ginepri returned to his glory days by beating Alex Bogomolov 7-5, 6-1 while John Isner edged Wayne Odesnik 7-5, 6-7 (2), 7-5.
