Seattle Mariners

Kansas City Royals Insights

• Kris Bubic – Over/Under 17.5 Pitching Outs (+100/-130)
  Throwing 96.1 adjusted pitches per GS this year on average, Kris Bubic falls in the 92nd percentile.
  Explain: Pitchers who average more pitches per game are more likely to go deeper into games and record more outs.
• Kansas City Royals – 2H Moneyline
  The Kansas City Royals bullpen profiles as the 8th-worst in the game, 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.

Seattle Mariners Insights

• Luis Castillo – Over/Under 4.5 Strikeouts (-125/-105)
  Given his large platoon split, Luis Castillo will have a tough matchup squaring off against 6 batters in the projected batting order who bat from the other side in today’s outing.
  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.
• Jhonny Pereda – Over/Under 0.5 Hits (-135/+105)
  Jhonny Pereda is an extreme groundball hitter and squares off against the strong infield defense of Kansas City (#1-best of the day).
  Explain: This player’s skill set matches up poorly with the opposing team’s defensive strength, which may lead to worse-than-usual performance.
• Josh Naylor – Over/Under 1.5 Total Bases (+155/-200)
  Josh Naylor pulls a lot of his flyballs (36.3% — 88th percentile) and has the good fortune of hitting them towards the league’s 4th-shallowest RF fences in today’s game.
  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.
