Tampa Bay Rays at Seattle Mariners: MLB Showdown Set for August 8, 2025

The Seattle Mariners will host the Tampa Bay Rays at T-Mobile Park on Friday, August 8, as both teams continue to battle for a playoff spot in their respective divisions. The Mariners, currently second in the AL West with a 63-53 record, look to extend their impressive four-game home winning streak. Meanwhile, the Rays, fourth in the AL East at 57-59, are eager to gain momentum on the road.

Pitching Probables

On the mound, the Rays turn to Drew Rasmussen (9-5, 2.81 ERA, 1.02 WHIP, 93 strikeouts), whose consistency has been a bright spot for Tampa Bay. The Mariners will counter with ace Luis Castillo (8-6, 3.22 ERA, 1.21 WHIP, 115 strikeouts), bringing his sharp command to the hill as Seattle seeks to keep its home winning streak alive.

Team Records and Performance

The Mariners boast a strong 34-25 record at home and have excelled in tight contests, currently holding a 24-15 record in games decided by one run. Conversely, the Rays are 25-29 on the road and will look to improve away from home, hoping their .315 team on-base percentage will provide the necessary spark against the Mariners’ pitching.

This meeting marks the first matchup between Tampa Bay and Seattle this season, adding an extra layer of intrigue to the series opener in Seattle.
