Seattle Mariners

Kansas City Royals Insights

• Kris Bubic – Over/Under 15.5 Pitching Outs (-125/-105)
  Throwing 96 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 9th-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 (-130/+100)
  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.
• Julio Rodriguez – Over/Under 0.5 Hits (-245/+185)
  The leading projection system (THE BAT X) projects Julio Rodriguez as the 12th-best batter in Major League Baseball when estimating 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.
• Cal Raleigh – Over/Under Total Bases
  Cal Raleigh pulls a high percentage of his flyballs (43.5% — 100th percentile) and is a great match for the park considering he’ll be hitting them towards MLB’s 9th-shallowest LF fences today.
  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.
