- Former world No. 1 Rafael Nadal reaches singles final in Chile comeback tournament
- Spaniard will seek his 37th clay-court title as he faces Horacio Zeballos in Vina del Mar
- Nadal can complete a Chilean conquest in the following doubles final on Sunday
- Roger Federer to return to action this week as he defends his title in Rotterdam
Rafael Nadal is on course for a comeback double as he bids for two titles at the VTR Open in Chile on Sunday.
The 11-time grand slam champion will seek his 37th clay-court crown and 51st overall when he takes on 73rd-ranked Argentine Horacio Zeballos in the singles final at Vina del Mar.
He will then team up with another Argentine, last year's tournament winner Juan Monaco, in the doubles final against Italy's Paolo Lorenzi and Potito Starace.
"I'm really happy with what I've been doing this week," said the Spaniard, who has dropped to fifth in the rankings after being sidelined for over seven months due to knee problems.
"I have a good feeling on the court, so I cannot ask for anything more. I will try to play better and better every day."
"I won't compare myself to seven months ago, it's just the first week of competition. It's a great feeling to be in a final match after so much time without playing."
Nadal's first real test of the week came in Saturday's semifinal against 26th-ranked French third seed Jeremy Chardy, but he had no problems in cruising to a 6-2 6-2 victory.
"I played well today, better than the days before, which is important," he said.
Zeballos, meanwhile, reached the second ATP World Tour final of his career -- the other being in St. Petersburg in 2009 -- by beating eighth-seeded compatriot Carlos Berlocq 6-3 7-6 (7-4).
Richard Gasquet became the first player to win twice on the ATP Tour this year as he beat compatriot Benoit Paire 6-2 6-3 in Sunday's final of the Open Sud de France in Montpellier.
The 10th-ranked Frenchman has a 14-1 record in 2013, having won the Qatar title in January before losing in the fourth round of the Australian Open.
In other men's news, Nadal's great rival Roger Federer will return to action in Rotterdam this week as he defends his World Tennis Tournament title.
The world No. 2, who lost to Andy Murray in the Melbourne semifinals last month, will play 60th-ranked Slovenian Grega Zemlja in his opening match.
In women's action, Petra Kvitova put the Czech Republic into the semifinals of Fed Cup on Sunday, as her 2-6 7-6 (7-3) 6-4 win over Samantha Stosur gave the two-time defending champions an unbeatable 3-0 lead against Australia in Prague.
The 2011 Wimbledon champion saved a match-point at 5-4 down in the second set against that year's U.S. Open victor Stosur.
Kvitova's teammates Andrea Hlavackova and Lucie Hradecka then beat Ashleigh Barty and Casey Dellacqua 6-0 7-6 (7-1).
The Czechs will next face Italy, who edged the United States 3-2 in Rimini.
Sara Errani and Roberta Vinci beat Liezel Huber and Varvara Lepchenko 6-2 6-2 in the decisive doubles rubber.
Russia also went to a decider against Japan before sealing a semifinal clash with Slovakia.
Japan leveled at 2-2 in Moscow as home No. 1 Maria Kirilenko was unable to play due to illness, as Ayumi Morita triumphed 6-4 6-1 against stand-in Elena Vesnina, but Ekatarina Makarova bounced back from her Saturday defeat to beat Kimiko Date-Krumm 6-1 6-1.
She then teamed up with Vesnina in a 6-2 6-2 doubles victory over Morita and Misaki Doi.
Slovakia took an unbeatable 3-1 lead against last year's finalists Serbia as Daniela Hantuchova won 6-3 6-2 against Vesna Dolonc.
