Ferrer, Berdych both climb in ATP ranking
Ferrer on Sunday collected his third Copa Claro title in Argentina. That snapped a seven-match finals losing streak, which began after he won the Copa Claro in 2013. He pushes past Juan Martin del Potro and back into the No. 4 ranking.
Del Potro was unable to repeat as ABN AMRO World Tennis Tournament champion in the Netherlands. That title eventually went to Berdych, who moves past Andy Murray for the No. 6 spot in the rankings. It was Berdych's first championship since October 2012 and ninth title overall.
Del Potro and Murray, now fifth and seventh in the rankings, respectively, both lost in the quarterfinals at Rotterdam.
Kei Nishikori picked up his second U.S. National Indoor Tennis Championships title Sunday. It was the Japanese player's sixth ATP title and fourth won in the United States. He moves up one place to 15th in the rankings.
The ATP again has three tournaments this week, including the inaugural Rio Open, which features world No. 1 Rafael Nadal, in his first action since the finals of the Australian Open, and Ferrer as the top seeds.
No. 10-ranked Jo-Wilfried Tsonga is the defending champion at the Open 13 event in Marseille, France, which has ninth-ranked Richard Gasquet as the first seed.
No. 12-ranked Tommy Haas leads the field at the Delray Beach Open in Florida.
