Read the Rays vs Mariners Prediction and Game Breakdown - August 7th, 2026

+100O/U: 7
(+100/-120)-120

Drew Rasmussen – Over/Under 17.5 Pitching Outs (-145/+110)
Tallying 91.9 adjusted pitches per start this year on average, Drew Rasmussen places in the 78th percentile.
Explain: Pitchers who average more pitches per game are more likely to go deeper into games and record more outs.
Chandler Simpson – Over/Under 0.5 Hits (-205/+155)
Chandler Simpson is penciled in 6th in the batting order in this game, which would be a downgrade from his 67% rate of hitting in the top-half of the lineup this season.
Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
Yandy Diaz – Over/Under 1.5 Total Bases (+125/-160)
Yandy Diaz has a 100th percentile opposite-field rate on his flyballs (43%) and sets up very well considering he’ll be hitting them towards baseball’s 4th-shallowest RF fences in today’s matchup.
Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.

Logan Gilbert – Over/Under 5.5 Strikeouts (-150/+115)
Given his reverse platoon split, Logan Gilbert will be at an advantage matching up with 7 batters in the projected offense who hit from the other side today.
Explain: A pitcher with a reverse platoon split will perform better against opposite-handed hitters (i.e. a right-handed pitcher will be better against a left-handed hitter). Holding this advantage against several hitters can have a huge impact on whether a pitcher will perform well or struggle on any given day.
Logan Gilbert – Over/Under 5.5 Strikeouts (-150/+115)
Cal Raleigh, the Mariners’s expected catcher in today’s game, projects as an elite pitch framer according to the leading projection system (THE BAT).
Explain: Pitch framing is a catcher’s ability to make a ball look like a strike to the umpire, “stealing” strikes for his pitcher. This leads to more positive outcomes (like strikeouts) and fewer negative ones (like walks or earned runs).

Seattle Mariners – Over/Under 3.5 Team Total (+105/-135)
The Seattle Mariners have hit the Team Total Under in 30 of their last 50 games (+8.40 Units / 15% ROI)
Tampa Bay Rays – Run Line -1.0 (+145)
The Tampa Bay Rays have hit the Run Line in 12 of their last 19 away games (+6.25 Units / 26% ROI)
Richie Palacios – Over/Under 0.5 Hits Runs and RBIs (-115/-115)
Richie Palacios has hit the Hits Runs and RBIs Under in 11 of his last 15 games (+7.20 Units / 39% ROI)
