Rays vs Mariners Preview
Bryan Woo is coming off a stellar outing against the Chicago White Sox. The right-hander just gave up two hits and one run in seven innings, with nine strikeouts.
Woo has a 2.17 ERA and a 0.79 WHIP at T-Mobile Park this season, and holds a 2.82 ERA across his last seven outings.
The Rays offense has been dreadful in August, ranking 28th in the majors with 64 wRC+.
Woo's rival today, former White Sox Adrian Houser, did not do well in his debut with Tampa Bay after being acquired at the trade deadline. However, he had a 2.42 ERA in July and is enjoying a turnaround season.
Houser already faced the Mariners this season and had great success. It was back on May 20, in his first start of 2025, and he held Seattle scoreless through six complete innings, conceding only two hits.
We should expect a low-scoring game in Seattle, and our Bet Labs recommendation for this game is to go with the under.
The Silent Sharp Unders system targets regular-season MLB games where both teams are performing well, yet the total has quietly dropped from open to close.
These are games featuring competent, winning teams with recent success, stable weather conditions, and closing totals in a common scoring range.
Despite both teams showing strength, the market subtly favors the under —likely due to matchup specifics, pitching, or pace factors.
By following this soft signal —when the public eye is more focused on win streaks and not totals—this system finds value in betting against inflated scoring expectations.
Pick: Under 7.5 (-105, DraftKings)
