The Tampa Bay Rays (68-46) are in the midst of a nine-game road trip out West and begin a three-game series against the Seattle Mariners (56-60) at T-Mobile Park on Friday night. This is the second and final regular-season meeting between the two teams, with the Rays already having won a three-game series against the Mariners right before the All-Star break.
The Rays continue to be one of the hottest teams in MLB, posting a 12-4 record since July 20 and holding a 4.5-game lead over the New York Yankees for first place in the AL East. Tampa Bay just swept Colorado to begin its West Coast road trip, averaging nearly nine runs per game in that series and earning a 4-0 shutout victory in Wednesday’s finale.
The Mariners are trying to keep pace in a competitive AL West, and while they were one game above .500 following their 8-0 shutout win against Cincinnati on July 20, Seattle now finds itself four games below .500 entering Friday. The Mariners are coming off a series loss to Detroit and were shut out 8-0 in the opener and 11-0 in Thursday’s finale.
Friday night’s pitching matchup features two veterans who have enjoyed plenty of success throughout their careers. Logan Gilbert and his 3.46 ERA are set to take the mound for Seattle, while All-Star right-hander Drew Rasmussen, who owns a 10-5 record, 2.91 ERA, and 0.93 WHIP, is scheduled to make his 22nd start of the season for the Rays. Both pitchers are in the 2026 American League Cy Young picture, with Gilbert tied for the fifth-shortest odds (+5000) and Rasmussen holding the third-shortest odds (+3000) at Hard Rock Bet Sportsbook.

Mariners vs. Rays Best Bet: Logan Gilbert Over 1.5 Earned Runs (-165)
Logan Gilbert has pitched really well all season, and while three earned runs can still represent a solid outing for any pitcher, he has allowed three or more earned runs in each of his last four starts. One of those just so happened to come against the Rays on July 11.
Gilbert allowed nine hits and four earned runs over 6.2 innings in the loss to Tampa Bay. While that’s still a respectable outing, it’s obviously over 1.5 earned runs, and the Rays are averaging 8.7 runs per game over their last three contests.
