Tampa Bay Rays
(-105/-115)-105
As the Tampa Bay Rays prepare to host the Seattle Mariners on September 2, 2025, they come off a commanding victory, having defeated the Mariners 10-2 in their last matchup. This game marks the second in a pivotal series between two teams vying for postseason positioning, with the Mariners currently holding a slight edge in the standings at 73-65 compared to the Rays’ 68-69 record.
Drew Rasmussen, projected to start for the Rays, is having an impressive season, ranking as the 15th best starting pitcher in MLB according to advanced metrics. With a solid Win/Loss record of 10-5 and an excellent ERA of 2.64, he has been a key contributor to the Rays’ rotation. However, projections indicate he may struggle today, as he is expected to pitch just 4.9 innings while allowing 2.3 earned runs and striking out only 4.6 batters on average.
On the other side, Bryan Woo takes the mound for the Mariners, boasting a slightly better ranking at 12th among MLB starters. With a 12-7 record and a stellar ERA of 2.95, Woo has also shown resilience, projecting to pitch 5.9 innings while allowing 2.5 earned runs. Both pitchers are right-handed and will face off against lineups that have shown contrasting offensive capabilities this season.
The Rays have an average offense, ranking 15th overall, but they excel in batting average, sitting 9th in the league. Meanwhile, the Mariners’ offense is 12th overall but struggles with batting average, ranking 21st. This discrepancy could play a crucial role in today’s match.
Betting markets have set the Rays’ moneyline at +100, suggesting a close contest. Given the projections and recent performances, Tampa Bay may have a path to capitalize on their home-field advantage, potentially defying expectations in this matchup. With a low Game Total of 7.5 runs, the stage is set for what could be a tightly contested battle.

Tampa Bay Rays Insights
- Drew Rasmussen – Over/Under 4.5 Strikeouts (-135/+105)It may come as a surprise, but fastballs are generally a pitcher’s least effective pitch.
