The Mariners announced that they released Matt Mangini to create 40-man roster space for Anthony Vasquez, who starts the second game of Seattle's double header against Cleveland today. Seattle placed Dan Cortes for the 15-day disabled list with a bruised left ankle in a related move.
Mangini, 25, opened the season on the Major League disabled list, but did not appear in a game for Seattle this year. He spent the season at Triple-A Tacoma, where he posted a .336/.399/.409 line in 259 plate appearances. The 2007 supplemental first round draft choice played in 11 games for the Mariners last year, appearing at third base and DH.
Mangini had been on the disabled list with post-concussion symptoms. He was involved in a home plate collision before the Triple-A All-Star break.
