MONTREAL — Fifth-seeded Andrey Rublev beat Matteo Arnaldi 6-4, 6-2 on Sunday in the National Bank Open semifinals after waiting out a rain delay early in the second set. Rublev, the 26-year-old Russian with victories this year in Madrid and Hong Kong, will face Alexei Popyrin of Australia in the final. Popyrin beat American Sebastian Korda 7-6 (0), 6-3. Arnaldi, from Italy, reached his first Masters 1000-level semifinal. Earlier Sunday in the quarterfinals, Popyrin topped fourth-seeded Hubert Hurkacz 3-6, 7-6 (5), 7-5, and Korda — the winner last week in Washington — beat second-seeded Alexander Zverev 7-6 (5), 1-6, 6-4. Rain washed out play Thursday night and all of Friday as remnants of Tropical Storm Debby rolled through, putting the event behind schedule.
