Review the Mariners vs Guardians Match Preview and Winning Probability - June 26th, 2026

-110O/U: 7.5
(-110/-110)-110

Luis Castillo – Over/Under 4.5 Strikeouts (-115/-115)
The Cleveland Guardians have 7 bats in the projected lineup that will receive the benefit of the platoon advantage against Luis Castillo today, which is especially problematic given his large platoon split.
Explain: Right-handed pitchers perform worse against left-handed hitters (and visa-versa). If several hitters hold this advantage against the pitcher, it can have a huge impact on whether he will perform well or struggle on any given day.
Luis Castillo – Over/Under 4.5 Strikeouts (-115/-115)
Projected catcher Cal Raleigh grades out as an elite pitch framer, via 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).

Rhys Hoskins – Over/Under 0.5 Hits (-130/+100)
Rhys Hoskins’s batting average talent is projected to be in the 8th percentile according to the leading projection system (THE BAT X).
Explain: THE BAT X is a highly sophisticated projection system that accounts for a multitude of factors and regularly tests among the most accurate systems available. Batting average is the most common measure of a player’s ability to generate hits.
Cleveland Guardians – 2H Moneyline
According to the leading projection system (THE BAT), the Cleveland Guardians’ bullpen grades out as the 3rd-best among all MLB teams.
Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.

Cleveland Guardians – Over/Under 3.5 Team Total (-120/-110)
The Cleveland Guardians have hit the Team Total Under in 11 of their last 18 games (+3.75 Units / 18% ROI)
