Jesse Levine and Steve Darcis reach final

American lefty Jesse Levine, trying to work his way back into the top 100 of the ATP Tour rankings, will play No. 2 seed Steve Darcis of Belgium on Saturday for the $100,000 yp Challenger of Dallas singles title.

The unseeded Floridian, ranked No. 160, set up the showdown with the 82nd-ranked Darcis with a 6-4, 7-5 victory over Germany's Stefan Seifert in Friday's semifinals at T Bar M Racquet Club.

Darcis posted a 7-6 (7-4), 6-3 triumph over sixth-seeded Izak Van Der Merwe of South Africa to clinch his spot in Saturday night's final.

The singles winner will earn $14,400, with the runner-up receiving $8,480.

American up-and-comer Jack Sock, meanwhile, has a shot to win a title as well when the Nebraska teenager and Nick Monroe meet the unseeded British pair of Chris Eaton and Dominic Inglot in Saturday's 6 p.m. doubles final.

Sock and Monroe, seeded No. 4 in the doubles draw, advanced with a 7-6 (7-5), 7-6 (7-4) victory over Alex Kuznetsov and Mischa Zverev in Friday's doubles semifinals.

Eaton and Inglot joined them with one of the upsets of the tournament, combining for a 4-6, 7-6 (7-5), 10-8 triumph over Mark Knowles and Robert Kendrick. Knowles is the world's former No. 1-ranked doubles player and has won Grand Slam doubles titles at the Australian, French and U.S. Opens.

The singles final between Levine and Darcis, who was once ranked as high as No. 44 in the world, will follow the doubles final.

The final day of the tournament, though, will start far earlier for tournament officials, who will be monitoring developments in Switzerland. That's where the untested doubles tandem of Mike Bryan and Ryan Harrison will try to secure the clinching point for the United States in a first-round Davis Cup match after Mardy Fish and John Isner posted surprise singles wins Friday over the heavily favored Stanislas Wawrinka and Roger Federer, respectively, on an indoor clay court.

Harrison, ranked 95th in the world in singles, had accepted a wild-card entry to the Challenger of Dallas. But the teenager had to withdraw when U.S. Davis Cup captain Jim Courier summoned Harrison to replace Mike's brother, Bob, who asked to skip the first-round tie so he could stay home in California to be with newborn baby daughter, Micaela.
