DENVER -- The Colorado Rockies have declined their half of a mutual option on Rafael Betancourt, making the right-handed reliever whos coming off an arm injury a free agent. J.J. Wilcox Cowboys Jersey . Betancourt was 2-5 with a 4.08 ERA and 16 saves for the Rockies last season before tearing a ligament in his pitching elbow. He considered undergoing platelet-rich plasma therapy to fix his arm, but announced in August his decision to have Tommy John surgery. The 38-year-old Betancourt spent parts of five seasons with the Rockies after being acquired from the Cleveland Indians in 2009. He had 31 saves for Colorado in 2012. Betancourt will receive a $250,000 buyout. Bruce Carter Cowboys Jersey . Harrison combined with four relievers on a five-hitter to get his first victory since September 2012, in his first home start since April 2013, and the Rangers won 5-0 Thursday night after being overwhelmed by the Rockies the previous three games. Emmitt Smith Jersey .Y. -- The Buffalo Sabres signed forward Nicolas Deslauriers to a two-year contract on Monday.VIERA, Fla. - The Washington Nationals filled the last clear-cut need on their roster on the opening day of spring training, acquiring catcher Jose Lobaton and two prospects from the Tampa Bay Rays on Wednesday for pitcher Nathan Karns. Lobaton gives the Nationals insurance behind fellow Venezuelan Wilson Ramos, who has never played in more than 108 games in a season because of various injuries. "Hes a capable backup," general manager Mike Rizzo said, "in case something does happen with Wilson." Lobaton, 29, started 76 games for the Rays last season and batted .249 with seven home runs and 32 RBIs. He was expendable because the Rays re-signed catcher Jose Molina and traded for Ryan Hanigan. Rizzo said Lobaton has above average metrics on defence. A notable exception is a 16 per cent success rate throwing out would-be base-stealers. "We feel that he throws well enough that he should be better than 16 per cent," Rizzo said. It speaks volumes about the Nationals confidence in their tallent-laden roster that a move for a backup can fill the last significant hole on the day that pitchers and catchers reported. Michael Irvin Cowboys Jersey. Barring injury, Rizzo wont be shopping during spring training. "Theres not an obvious spot that we need to address," Rizzo said. "But, as we say, if an opportunity arises, well be aggressive and open-minded about it." The Nationals are giving up a top prospect in the 26-year-old right-hander Karns, who three made starts in his first taste of the major leagues last season, but theyre adding a pair of 22-year-olds from the Jays pool of talent: outfielder Drew Vettleson and left-handed pitcher Felipe Rivero. Karns would have been in a crowded race for the No. 5 spot in the rotation. The trade for a younger pitcher alleviates part of that logjam and helps the Nationals stagger their pitching prospects. To make room for the new players on the 40-man roster, Washington placed right-handed pitcher Erik Davis on the 60-day disabled list with a sprained right elbow. ' ' '
