The Mariners should get a boost to their lineup Tuesday as Robinson Cano returns from an 80-game suspension. Mariners ace James Paxton struck out a career-high 16 batters the last time he faced Oakland despite eventually setting for a no-decision. Mike Fiers was impressive in his A's debut last week against the Dodgers, but has a career 6.21 ERA against the Mariners and was roughed up the last time he faced them. Take Seattle to even this series in critical stretch for the AL wild-card race.
