RIO DE JANEIRO — Defending champion Cameron Norrie has been bundled out of the Rio Open with a shock straight sets defeat to qualifier Mariano Navone on Saturday.

The Argentine, 22, beat the second-seeded British player 6-4, 6-2 to advance to his first tour-level final where he will play compatriot Sebastián Báez.

Norrie didn’t offer much resistance to the 113th-ranked Navone despite having become the favorite to win the clay-court tournament again after Carlos Alcaraz, Stan Wawrinka and Nicolás Jarry were all beaten or retired injured.

In the earlier semifinal, fifth-seeded Báez topped his Argentine compatriot Francisco Cerundolo 7-5, 6-0 to advance to his fifth and biggest tour-level final.

“Argentina has many players and many very good players,” the 30th-ranked Báez said. “We are using this [tournament] to climb up, we are young. I like to play in Rio, come to Brazil. When I don’t play against a Brazilian I feel like a local.”
