(Toronto, ON)  --  The Mariners' hopes of a Wild Card berth are fading fast, after a 1-0 loss to the Blue Jays in Toronto.  Rookie Taijuan Walker gave up only one run on four hits and struck out six over eight innings, but Seattle managed only three hits.  The Mariners remain three games back in the AL Wild Card race with only four games left in the regular season.  Seattle and Toronto will wrap up their four-game series this afternoon.
