Seattle Mariners Insights

• Luis Castillo – Over/Under 4.5 Strikeouts (-155/+120)
  The Cleveland Guardians have 9 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 (-155/+120)
  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).

Cleveland Guardians Insights

• Kahlil Watson – Over/Under 0.5 Hits (-135/+105)
  The leading projection system (THE BAT X) projects Kahlil Watson in the 12th percentile as it relates to his batting average skill.
  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 5th-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.
