Boston’s recent form, depth in the rotation, and home edge at Fenway shape trader expectations, though Seattle’s rotation led by Logan Gilbert, George Kirby, and Bryan Woo offers matchup resistance. The Mariners sit three games back in the AL West and remain in the wild-card mix behind an AL West division race that features sub-.500 teams; their easiest remaining schedule in baseball, highlighted by upcoming series against the A’s, Angels, and Rockies, adds playoff-context urgency. Cal Raleigh’s recent power surge and the club’s road performance factor into assessments of Seattle’s chances in this AL East road test.
