RIO DE JANEIRO, Brazil -- Rafael Nadal is back -- and its all about his back. Top-ranked Nadal injured his back warming up for the final of the Australian Open almost three weeks ago, eventually losing against Stanislas Wawrinka -- a match he was an overwhelming favourite to win. Nadal has practiced little since then, getting treatment at home in Mallorca. His first test comes in next weeks Rio Open, a new stop on the ATP Tour. "Well have to see how it goes," he said Friday. "I hope I can tolerate it." Nadal knows the clock is ticking. He made a comeback last season from a left knee injury, which kept him out of the 2012 London Olympics. Hes won 13 Grand Slams. Hes one behind Pete Sampras, and hes closing in on Roger Federers record of 17. Hes sure one got away in Australia. "In Australia I lost a good opportunity to add another Grand Slam," Nadal said. "It didnt happen. The opportunities are not infinite. They have an expiration date." Nadal has played more than 11 years as a professional, perhaps sustaining some injuries because of his big swings and attacking temperament. "I heard a lot of times in my career that I will have a shorter career because of my style of game," he said. "I really think its something that will not happen. If I stopped today, I already will have more than 11 years on tour." The Spaniard said hes still motivated, positive about the 2014 season. "I cannot predict the future for how long I will be here competing well," he said. "I cant say when thats going to end. The only thing I can say is today I feel happy about what I am doing. I am feeling motivation mentally to keep playing, to keep competing well." Hell be 30 when the 2016 Rio Olympics begin. He called winning gold in the 2008 Beijing Olympics "one of the best experiences" of his career. "It was a very hard moment for me when I made the decision not to play the Olympic Games in London," Nadal said. "After that, I always say my goal is to arrive to the 2016 Olympic Games here in Rio."

ARLINGTON, Texas -- When Kevin Kouzmanoff was riding the buses in Double-A two seasons ago, he kept his focus on returning to the majors and providing the kind of production that he is now delivering for the Texas Rangers. "You never know what can happen in baseball," Kouzmanoff said after helping the Rangers beat the Seattle Mariners 8-6 Thursday. "Here I am. Its great to be back." Kouzmanoff hit two doubles and scored twice. Texas lost the opener of the four-game series on Monday night, but won the last three. The 32-year-old Kouzmanoff is hitting .414 since being promoted from Triple-A Round Rock on April 9 after starting third baseman Adrian Beltre strained his left quadriceps. Kouzmanoff has hit in all eight games in which he has played, beginning with a pinch-hitting appearance followed by seven straight starts. Beltre was put on the 15-day disabled list Sunday. Shin-Soo Choo homered for Texas and J.P. Arencibia had a pair of RBI groundouts. Robinson Cano hit his first homer for the Mariners, going back-to-back with Corey Hart. Cano is in a 3-for-18 slump. The Rangers broke a 6-all tie in the fifth inning when Arencibia drove in a run with a grounder and Mitch Moreland scored on a wild pitch by Joe Beimel (0-1). Pedro Figueroa (2-1) was the second of five Texas relievers who held Seattle scoreless. He earned his second victory in less than 24 hours -- he was Wednesday nights winner when the Rangers rallied for two runs in the bottom of the ninth for a 3-2 victory. Kouzmanoff was a major league regular from 2007-11 for three clubs before spending the past two seasons in the minor league systems of Kansas City and Miami. He signed a minor league contract with Texas in December and hit .370 during spring training. Kouzmanoff was the Rangers last cut in spring training and sent to Round Rock when the club decided to complete its opening day roster with more middle-infield help because second baseman Jurickson Profar began the season on the disabled list.dddddddddddd. "Im not the player that Beltre is. Hes an unbelievable player," Kouzmanoff said. "We all have to do things that are us." Asked the source of his hot streak, he said, "Eating oatmeal every morning for breakfast." Texas Tanner Scheppers, in his first season as a big league starter, made the shortest of his four starts and was victimized by the big inning for the third time. He took the mound with a 4-0 lead and then gave up six runs in the third while recording just one out. "It doesnt feel good," said Scheppers, the Rangers eighth-inning setup man for most of last season. "Luckily, the bullpen picked me up. The offence went out and scored runs. You cant ask for any more than that." Scheppers said he wasnt worried about being sent back to the bullpen. Rangers manager Ron Washington echoed that sentiment. "Its nothing that has crossed my mind," Washington said. "We know its a work in progress." The Rangers made it 6-all by chasing Mariners starter Erasmo Ramirez with two runs in the third. In his last three starts, Ramirez has lasted no more than five innings and allowed 13 earned runs and 18 hits. Hart reached base four times, with a double and two walks in addition to his team-leading fourth homer. He played right field for his first outfield appearance since July 2012. "Down 4-0 at one point and to battle back and take the lead, we definitely have fight in this team," Hart said.
