@

Boston Red Sox

Baltimore Orioles Insights

• Trevor Rogers – Over/Under 4.5 Strikeouts (+100/-130)
  Out of all starting pitchers, Trevor Rogers’s fastball spin rate of 2441 rpm ranks in the 85th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Coby Mayo – Over/Under 0.5 RBIs (+230/-315)
  Boston’s #1-ranked outfield defense of all teams on the slate poses a formidable challenge for Coby Mayo, who tends to hit a lot of flyballs.
  Explain: This player’s skill set matches up poorly with the opposing team’s defensive strength, which may lead to worse-than-usual performance.
• Baltimore Orioles – 2H Moneyline
  The Baltimore Orioles bullpen grades out as the 4th-worst in MLB, according to 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.

Boston Red Sox Insights

• Brayan Bello – Over/Under 3.5 Strikeouts (-160/+125)
  Because flyball hitters have a substantial edge over groundball pitchers, Brayan Bello and his 50.6% underlying GB% (according to the leading projection system, THE BAT) finds himself in a troublesome position in this game being matched up with 2 opposing GB hitters.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create diminished performance across all categories and hidden value few are considering.
• Ceddanne Rafaela – Over/Under 0.5 Hits (-270/+200)
  Ceddanne Rafaela has primarily hit in the back-half of the batting order this season (57% of the time), but he is projected to hit 2nd in the lineup in today’s game.
  Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
• Carlos Narvaez – Over/Under 0.5 RBIs (+195/-265)
  Carlos Narvaez has a 94th percentile opposite-field rate on his flyballs (37%) and is a great match for the park considering he’ll be hitting them out towards MLB’s 3rd-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.
