NEW YORK -- Entering a big league ballpark will be a bit like going through an airport by 2015. Shoes Discount Sale Online . Major League Baseball has told its 30 teams they must implement security screening for fans by then, either with hand-held metal detection or walk-through magnetometers. "This procedure, which results from MLBs continuing work with the Department of Homeland Security to standardize security practices across the game, will be in addition to bag checks that are now uniform throughout MLB," baseball spokesman Michael Teevan said Tuesday. The Seattle Mariners announced Tuesday that fans entering Safeco Field will have to walk through metal detectors starting with this years opener. Boston, the New York Mets, Oakland, Pittsburgh and San Francisco were among the teams that experimented with screening at times last year. Security gained more intense focus after three people were killed and more than 260 wounded in when two bombs were set off at the Boston Marathon finish line. "We conducted testing of these measures at the All-Star game and at both World Series venues last year, and we were pleased that it was effective and received without issue from fans," Teevan said. MLB is being assisted by CEIA USA Ltd., which manufactures walk-through metal detectors, and the security company GSIS. Big league teams have generally limited bags that fans bring to 16 inches by 16 inches by 8 inches. In an effort to increase security this season, the NFL limited the size and type of bags fans can bring to games. With the exception of medically necessary items, only clear plastic, vinyl or PVC bags no larger than 12 inches by 6 inches by 12 inches have been allowed. One-gallon clear plastic freezer bags also were permitted along with clear plastic bags approximately the size of someones hand. Shoes Clearance Sale Online .

The Toronto Blue Jays star won his second consecutive Hank Aaron Award as the most outstanding offensive performer in the AL on Monday after votes by fans and a panel of Hall of Famers were tallied.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.

"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.
