The Tampa Bay Rays (57-59) travel to T-Mobile Park on Saturday to face the Seattle Mariners (62-53) in what could be a make-or-break series for both clubs fighting to stay relevant in their respective divisions.
Seattle enters riding hot form with six wins in their last seven games and sits just 1.5 games back of first place in the AL West, while Tampa Bay has struggled recently with six losses in their last nine contests and trails the AL East by 11 games.
The pitching matchup features Tampa Bay's Joe Boyle, who's been sharp lately with a scoreless five-inning effort against the Dodgers, against Seattle's Logan Evans, who's allowed nine runs over his last two starts and could be vulnerable on the mound.

Seattle Mariners vs. Tampa Bay Rays preview
The Mariners enter Saturday's matchup riding high after sweeping the White Sox and winning six of seven, sitting just 1.5 games back in the AL West division race.
Tampa Bay counters with their own momentum despite recent struggles, as starter Joe Boyle has found his groove with a stellar 2.30 ERA this season and blanked the Dodgers over five innings in his last outing.
Seattle's Logan Evans faces pressure after getting roughed up in consecutive starts, surrendering nine runs across his last two appearances while the Rays have historically owned this matchup with six wins in the last nine meetings.
Both clubs boast strong bullpens ranking in the top 10 for ERA, but Tampa Bay's pitching staff leads in quality starts and WHIP despite playing without eight injured arms.
Cal Raleigh's 42 home runs anchor Seattle's offense while Junior Caminero paces Tampa Bay with 30 long balls, setting up an intriguing power vs. pitching battle at T-Mobile Park.
With Tampa Bay 11 games back in the AL East and Seattle chasing division leaders, this series carries different stakes but both teams need wins to stay relevant in their respective races.
