Wawrinka retires injured vs Lopez at Swiss Open
Stanislas Wawrinka retired from his quarterfinal match against Feliciano Lopez with back injury.
GSTAAD (AP) - A day after Roger Federer lost at the Swiss Open citing back pains as a problem, local favorite Stanislas Wawrinka retired from his quarterfinal match Friday with the same injury.
The second-seeded Wawrinka was unable to continue after a medical timeout more than two hours into his match with Feliciano Lopez, who was leading 6-4, 2-6, 4-3 at the time.
Wawrinka, ranked No. 10, extended an unhappy run at his home tournament. He has won only five matches all against players outside the top 50 in seven visits since reaching the 2005 final.
The fifth-seeded Lopez will face Robin Haase of the Netherlands in the clay-court tournament on Saturday.
The 57th-ranked Haase beat 2011 champion Marcel Granollers of Spain 5-7, 6-3, 7-6 (5) in 2 hours, 30 minutes.
Federer s conqueror, Daniel Brands of Germany, failed to build to build on that success in losing 6-3, 6-4 to Victor Hanescu.
Hanescu, the 2008 Gstaad champion, forced one service break in each set to ease to victory.
Mikhail Youzhny will next face Hanescu after beating fourth-seeded Juan Monaco of Argentina 5-7, 6-4, 7-6 (7).
The sixth-seeded Russian saved three match points in the deciding tiebreaker.
