Mariners designate Jason Bay for assignment
Bay, 34, signed with Seattle this winter after being released by the Mets, and he hit .204 with 11 home runs and 20 RBI in 68 games with the Mariners this season before being let go when Seattle activated Michael Morse off the disabled list.
The Mariners now have 10 days to trade or release Bay or attempt to outright him to the Minor Leagues.
A former All-Star in both Boston and Pittsburgh, Bay signed a four-year, $66 million deal with the Mets in November 2009 but was released last November, agreeing to a buyout that would see him receive the remainder of the $21 million the Mets owed him, albeit with some of that money deferred.
Bay then signed a non-guaranteed deal with Seattle in December that would pay him a base salary of $1 million with the chance to earn up to $2 million in incentives if he made the Major League roster.
The 2004 NL Rookie of the Year, Bay is a .266 career hitter with 22 home runs in 11 seasons with the Padres, Pirates, Red Sox, Mets, and Mariners.
