SEATTLE — The Seattle Mariners host the Philadelphia Phillies at T-Mobile Park on Tuesday in an interleague meeting with playoff implications for both clubs. First pitch is scheduled for the evening.

The Mariners are working to solidify their standing in the American League West and wild card race. Seattle's homegrown pitching core has anchored the club's contention through late August.

Philadelphia is chasing momentum in a competitive National League field. The Phillies' veteran-laden lineup, reinforced at the trade deadline, is driving their push for an October return.

Interleague fixtures late in the season magnify small margins. Both managers are expected to deploy their best arms, and the result could shape playoff seeding and bullpen usage in the closing weeks.

The series represents a demanding road stretch for Philadelphia and a crucial homestand for Seattle, with each victory increasing in value as the regular season enters its final month.
