The Canadian, who missed out on a chance to face Murray when the Britain withdrew from a Davis Cup tie last month, lost the first set on a tie break to the Taiwanese player.

But he then showed good fighting qualities to win the next two sets 6-4, 6-3.

It came on a good day for qualifiers as Peter Gojowczyk of Germany also triumphed over three sets against American opponent Reilly Opelka.

He recovered from a third set wobble to win 6-4, 3-6, 6-1.

There was a better result for Opelka's compatriot Bjorn Fratangelo as the world number 112 won 6-2, 6-2 over Australia's world number 42 Bernard Tomic.

Fratangelo will now face Czech Republic's 13th seed Tomáš Berdych in the second round.

Barbados' Darian King was another qualifier to progress after beating Georgia's Nikoloz Basilashvili 7-5, 7-5.

Portugal's João Sousa was another first round winner after beating Diego Schwartzman of Argentina 4-6, 6-3, 6-4.

First round action will continue tomorrow before the top seeds enter the draw in the second round on Saturday (March 11).

Serbia's Jelena Jankovic was among the winners as first round action continued in the women's draw.

The former world number one was pushed hard by the American wildcard before winning 6-2, 3-6, 6-3.

She will face another American in Venus Williams in the next round.
