Sebastian Baez has claimed the fifth and biggest title of his career…

On Sunday, the 23-year-old Argentine professional tennis player defeated compatriot Mariano Navone 6-2, 6-1 at the Rio Open.

The fifth-seeded Baez wasn’t seriously challenged by the 22-year-old Navone, a qualifier, in the final of the clay-court tournament.

Neither of the two Argentinians had been among the favorites to lift the title, but defending champion Cameron Norrie, Carlos Alcaraz, Stan Wawrinka and Nicolás Jarry had all stumbled.

Baez is the second Argentinian to lift the trophy, with Diego Schwartzman the first in 2018.

Baez is set to climb to a career-high No. 21 in the rankings on Monday, from his current No. 30.

Navone will become a top 100 player for the first time, reaching No. 60 after Rio.
