Great Britain's Johanna Konta bowed out of the first round of the Coupe Banque Nationale in Quebec on Monday to Asia Muhammad.

The 23-year-old put up a brave fight against her American opponent in a match which lasted more than two-and-a-half hours.

Muhammad eventually prevailed 6-2 6-7 (0-7) 7-6 (7-4) in Canada.

Elsewhere, Shelby Rogers made short work of Czech qualifier Tereza Martincova. The fourth-seeded American raced to a 6-1 6-3 win in an hour and five minutes.

There was a third American first-round win as Madison Brengle defeated compatriot Samantha Crawford 6-3 6-3, but Germany's Tatjana Maria upset another player from the United States, seventh seed Anna Tatishvili, to win 7-6 (11-9) 6-4.

There were no such problems for the fifth seed, Julia Goerges from Germany, who swept aside Canadian wildcard Stephanie Dubois 6-1 6-2, while Kazakhstan's Sesil Karatantcheva beat American Sanaz Marand 3-6 6-1 7-6 (8/6)
