Australian Nick Kyrgios qualified for the Montreal Open on Tuesday, beating Argentina’s Sebastián Báez 6-4 in identical quarters, settling for a second-round duel against first-seeded Russian Daniil Medvedev .

Kyrgios just won the Washington Open last week. He ended a title drought that had plagued him for three years there, to achieve seven singles trophies during his career on the ATP Tour.

Medvedev, the defending tournament champion who qualified directly for the second round, will face Kyrgios on Wednesday.

In other first-round matches, Britain’s Andy Murray, once world number one, lost 6-1, 6-3 to local Taylor Fritz.

Australian Alex de Minaur beat local Denis Shapovalov 7-6, 7-6(4) in a first round match which was postponed the day before due to rain.

The two players were tied 3-3 in Monday night’s second set tie-break when the interruption occurred. Once back on center court at the IGA Stadium, Shapovalov only managed to earn one of the five points.

The 22nd-ranked Canadian, one under De Minaur, has managed just one win in his last nine games.

Shapovalov gave the first break of service of the match to conclude the first set. He was more aggressive in the second set and looked set to force a deciding set, before the rain started.

When play resumed, the Canadian had served but double faulted. Two backhand misses gave De Minaur a pair of match points which he converted at the first opportunity.

In other encounters, American Tommy Paul beat local Vasek Pospisil 6-4, 6-4 and 15th-seeded Bulgarian Grigor Dimitrov picked up a 6-4, 7-5 victory over Alexis Galerneau, another Canadian tennis player, who came to the tournament by invitation. .

Spaniard Pablo Carreno Busta stunned 11th-seeded Matteo Berrettini to win 6-3, 6-2. Marin Cilic, the 13th seed, advanced 6-3, 6-2 over fellow Croatian Borna Coric.
