At the end of 2012, left fielder Jason Bay signed a 1-year, $1 million deal with the Seattle Mariners, but had to spend spring training trying to claim a roster spot. Bay, 34, had a solid run with the Red Sox in 2008-2009, but then his performance slowly declined.
Bay was a highly sought free agent at the end of 2009 and signed with the New York Mets, but his good fortune ended there. He was out for much of 2010 with concussion-like symptoms and only hit four home runs during the three seasons he spent with New York. Bay is hitting .220 with 11 home runs and 20 RBIs in the first half of 2013 for the Mariners.
