Rays pounded Seattle pitching to a 10-2 win in Tampa, riding a early offensive barrage and a late burst to pull away. Castillo labored four innings, surrendering five runs on five hits, including a three-run homer that doomed his line, while Emerson Hancock looked sharp in a bullpen cameo but the Rays kept a relentless attack. Tristan Gray provided a late dagger with a two-run shot in the eighth, and Randy Arozarena returned to a roaring ovation with a productive, speedy plate appearance. Seattle managed just 10 hits and left most rallies stranded, exposing gaps in both its rotation and lineup against Tampa Bay’s attack.

Fantasy takeaway: Castillo’s recent form remains precarious in hostile environments, so keep him on the bench in tough park starts until he proves droughts can end. The Rays’ home power remains a reliable source of fantasy upside, while Hancock’s velocity spike is intriguing for bullpen usage. In deeper leagues, follow Rays’ hot handers and monitor Seattle’s bullpen rollouts and split-starts as they navigate a challenging schedule.

The Seattle Mariners made a significant move by claiming outfielder Leody Taveras from the Texas Rangers, a rival in the American League West. Taveras, who played a crucial role in the Rangers' World Series victory against Arizona, has been inconsistent this season, batting just .241 with one home run and six stolen bases in 30 games. The Mariners are assuming the remaining $3.25 million on his contract, hoping to revitalize his career.

In other roster adjustments, utility player Dylan Moore has been reinstated from the injured list, while Samad Taylor has been optioned to Triple-A Tacoma. Right-hander Luis F. Castillo has been designated for assignment after struggling with a 7.71 ERA in his two starts this season. Moore was performing well before injury, boasting a .286 batting average with six homers and nine RBIs, indicating the Mariners’ intent to strengthen their lineup.
