Tampa Bay Rays

Seattle Mariners Insights

• Luis Castillo – Over/Under 17.5 Pitching Outs (-110/-120)
  Compared to the average starting pitcher, Luis Castillo has been given a longer leash than the typical pitcher this year, recording an extra 6.3 adjusted pitches each outing.
  Explain: Pitchers with a longer leash are more likely to go deeper into games and record more outs.
• Randy Arozarena – Over/Under 0.5 Hits (-240/+180)
  Randy Arozarena’s batting average talent is projected to be in the 85th 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.
• Luis Castillo – Over/Under 4.5 Strikeouts (-105/-125)
  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).

Tampa Bay Rays Insights

• Nick Martinez – Over/Under 4.5 Strikeouts (+115/-150)
  Due to his reverse platoon split, Nick Martinez will be in a good position being matched up with 7 bats in the projected batting order who bat from the other side in this matchup.
  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.
• Chandler Simpson – Over/Under 1.5 Hits (+190/-255)
  Chandler Simpson is projected to hit 6th in the batting order in this matchup, which would be a downgrade from his 70% rate of hitting in the top-half of the batting order 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.
• Tampa Bay Rays – 2H Moneyline
  According to the leading projection system (THE BAT), the Tampa Bay Rays’ bullpen ranks as the 7th-worst among all the teams in the majors.
  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.
