Rebecca Marino of Vancouver started strong, faded, then scrambled to survive two match points before rallying to save her bid to qualify for the 145th U.S. Open Tennis Championships on Monday in New York.

Marino won the first set of her women's singles match 6-3 in 31 minutes against Lanlana Tararudee, but then lost 6-2 and was down 5-3 to the 21-year-old from Thailand before rallying for a 7-5 win in a match that took two hours, 11 minutes to complete.

Marino had more double faults than Tararudee (8-6), fewer aces (9-8) and few games won in a row (7-6). But she came up big in the third set, breaking Tararudee at 5-3 and at 5-5 to engineer the thrilling comeback.

Marion won four of five break points, while Tararudee only won four of 11. The Canadian won 67 per cent of her points on first serve, compared to 73 for her young rival.

The 34-year-old Marino advances to play Mai Hontama of Japan.
