Teen Andy Murray faced a challenge at the Regions Morgan Keegan Championships for the second straight day, and once again came out on top.

The 18-year-old mustered a late and fatal break against South African Rik De Voest to seal the 7-6(4), 3-6, 7-5 victory and earn his berth in the Memphis quarterfinals.

With his winning effort Thursday, Murray will earn enough ranking points to displace Tim Henman as the top British player when the INDESIT ATP Rankings are released Monday. The Scot, who rose 13 places to a career-high No. 47 following his SAP Open title victory, stood just within reach of No. 40 Henman and No. 43 Greg Rusedski to began his week in Memphis.

Murray will come up against indoor specialist Robin Soderling for the second straight week when the two go head-to-head on Friday. Murray bounced back from a set down in last week's quarterfinal match in San Jose to defeat the Swede en route to his first career ATP title.

Soderling ousted defending champion Kenneth Carlsen 7-6(3), 6-4 in earlier second-round action Thursday. The Swede, who crushed 2005 finalist Max Mirnyi 6-0, 6-1 in the first round, is 33-14 career indoors, compared to 30-47 career outdoors.

French qualifier Julien Benneteau set up a quarterfinal showdown with top seed Andy Roddick by beating Belgian eighth seed Xavier Malisse 7-6(4), 6-4 Thursday. Benneteau is playing just his second ATP-level match of the season.

He reached the third round of the Australian Open, where Roddick dismissed him 6-1, 6-2, 6-2. In his only other tournament apperance this year Benneteau fell in the first round of the Andrezieux Challenger to countryman Thierry Ascione.

Kristof Vliegen delivered better news to Belgian fans when he defeated American Paul Goldstein 6-1, 6-4 to reach the quarterfinals.

Chilean qualifier Paul Capdeville withstood 19 aces from 6' 10'' Croatian Ivo Karlovic to reach the quarterfinals with a 7-6(1), 3-6, 7-5 win.

Russian Dmitry Tursunov continued his best-ever start to a season with a 6-0, 6-7(3), 6-3 win to reach the quarterfinals for the third time this year (Doha, Sydney). Tursunov is 10-5 on the season and rapidly closing on his best-ever season record of 17-15.

Tursunov will next meet Tommy Haas, who defeated Vincent Spadea 7-6(7), 6-1. In his previous event appearances this year, Haas reached the semifinals in Doha and the fourth round of the Australian Open - both times falling to World No. 1 Roger Federer - and walked away with the trophy in Delray Beach.
