+165O/U: 7
(-115/-105)-195

Robbie Ray – Over/Under 5.5 Strikeouts (+105/-135)
Robbie Ray’s higher usage rate of his secondary pitches this year (53.2% vs. 48% last season) ought to work in his favor consider they are typically much more effective than fastballs.
Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
Heliot Ramos – Over/Under 0.5 Total Bases (-180/+135)
This season, Heliot Ramos has experienced a significant improvement in his exit velocity on flyballs, now sitting at an average of 96.4 mph compared to last year’s 93.3 mph mark.

The San Francisco Giants have 4 bats in their projected offense today with a high (i.e. over 27%) underlying K% (per the leading projection system, THE BAT X) (Grant McCray, Willy Adames, Bryce Eldridge, Drew Cavanaugh).
Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts

Seattle Mariners – Moneyline (-195)
The Seattle Mariners outfield defense profiles as the 2nd-worst out of every team on the slate today.
Explain: Defense is an integral part of preventing (or, in this case, allowing) hits and runs.
Mitch Garver – Over/Under 0.5 Total Bases (-110/-120)
Extreme flyball bats like Mitch Garver usually hit worse against extreme flyball pitchers like Robbie Ray.
Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create diminished performance across all categories and hidden value few are considering.
Seattle Mariners – 2H Moneyline
The Seattle Mariners bullpen grades out as the 8th-worst in Major League Baseball, via the leading projection system (THE BAT).
Explain: Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game’s runs.
