Seattle at Tampa Bay

Seattle was shut out 2-0 by Miami on Wednesday, five hits and two walks and nothing to show for it, the latest entry in an offensive slump that's left the Mariners hitting under .200 with runners in scoring position since mid-June. That cold offense walks into Tropicana Field against Nick Martinez, who has been one of the steadier arms in the league all year, with a 2.60 ERA built on rarely beating himself with walks. Luis Castillo draws the start for Seattle, and his season ERA sits near 4.80, numbers that would normally invite scoring, but this Mariners lineup hasn't given opposing pitchers much to worry about lately, regardless of who's on the mound. Tampa Bay's own offense has been steady rather than explosive, and a dome game limits the kind of wind-aided scoring that can wreck a total. Two competent-enough arms, a Rays club playing its usual clean brand of baseball at home, and a Seattle lineup that's forgotten how to string hits together add up to a total more likely to stay under than not. Take the UNDER tonight.
