Major League Baseball is suspending Miami Marlins reliever Juan Carlos Oviedo – formally known as Leo Nunez - for six weeks due to years of identify fraud.Oviedo is currently in his home country of the Dominican Republic finishing his community service. Once completed, he will get a work visa to pitch in the United States but must sit out six weeks, starting on Opening Day of the season.Oviedo turned himself in at the request of his dying father after going under the name Nunez - his best friend's name - for 17 years. He originally took the false name to appear 16 instead of 17 in order to sign a more lucrative contract. He pitched under the false name for seven years in the majors.Last year, he recorded 36 saves in 42 opportunities. The Marlins will not have to pay part of his $6 million salary for 2012 while he’s suspended.
