Canada's Felix Auger-Aliassime and Greece's Stefanos Tsitsipas will meet in the final of the Dubai Tennis Championships after they won their semifinal matches on Friday.

Tsitsipas, the No. 4 seed, was the only seeded player remaining in the draw. He posted a 6-4, 6-4 win over Tallon Griekspoor of the Netherlands, who upset No. 1 seed Daniil Medvedev in the quarterfinals.

Tsitsipas won points on 91 percent of his first serves and didn't face a break point.

Auger-Aliassime was pushed by French qualifier Quentin Halys and came back from a set down to win 5-7, 6-4, 6-3. Auger-Aliassime has won an ATP Tour-leading 16 matches this season, including titles in Adelaide and Montpellier.

Abierto Mexicano Telcel

Eighth-seeded Tomas Machac of the Czech Republic advanced to the second final of his ATP Tour career, beating the United States' Brandon Nakashima 6-4, 1-6, 6-4 in Acapulco, Mexico.

Machac dropped his only previous title match on tour, last year in Geneva, Switzerland. The final set on Friday was on serve into the last game, when Machac broke Nakashima on his third match point.

His opponent on Saturday will be either ninth-seeded Denis Shapovalov of Canada or Spain's Alejandro Davidovich Fokina, who faced off in the second semifinal Friday night.

Movistar Chile Open

Top-seeded Francisco Cerundolo survived a quarterfinal challenge from fifth-seeded Argentine countryman Tomas Martin Etcheverry, rallying for a 4-6, 6-3, 7-5 victory.

Cerundolo got the only service break of the third set in the penultimate game, then sealed the win on his second match point.

In another all-Argentine matchup, Camilo Ugo Carabelli downed Federico Coria 6-4, 6-3.

Carabelli next draws another Argentine, third-seeded Sebastian Baez, who ousted Bosnia's Damir Dzumhur 6-4, 6-4. Serbia's Laslo Djere got past Portugal's Jaime Faria 7-6 (5), 4-6, 6-4 to earn a semifinal date with Cerundolo.
