(Seattle, WA)  --  The Mariners return home tonight having lost six straight.  They'll look to turn that around against the Reds.  Rookie Justus Sheffield will take the ball for Scott Servais' team.  The southpaw is still in search of his first win as he's 0-and-1 with a 5.51 ERA in four starts this year.  Trevor Bauer will toe the slab for Cincinnati.  He's 10-and-12 with a 4.60 ERA, but just 1-and-4 since joining the Reds.
