Just when it seemed like Rafael Nadal had nothing left to prove, the Spaniard helped end his 2019 season with a Davis Cup title. 

Even with a season of nagging injuries and younger players threatening to overtake the top ranks, the 33-year-old led the Spanish team to the Davis Cup title by winning all eight of his matches.

Though the 18-team final format was less than ideal for the majority of fans, Spain celebrated their 2-0 victory over Canada with as much gusto as they celebrated their previous five Davis Cup titles.

Yet Nada's defeat over Denis Shapovalov to seal the victory may not have been the greatest performance of the week. Roberto Bautista Agut was coping with the death of his father. He came back to the court for the final the day after the funeral to defeat Felix Auger-Aliassime, 7-6 (3), 6-3.

It was the sixth Davis Cup title for Spain and Nadal's fifth time being a part of the journey, having previously suited up for Spain all the way to the trophy in 2004, 2008, 2009 and 2011.

The tournament is set to return to Madrid with 18 teams in 2020.
