New York Mets Insights

• David Peterson – Over/Under 4.5 Strikeouts (-115/-115)
  Among all starting pitchers, David Peterson’s fastball spin rate of 2182 rpm grades out in the 24th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Carson Benge – Over/Under 1.5 Hits (+180/-235)
  Carson Benge has primarily hit in the back-half of the lineup this year (68% of the time), but he is penciled in 1st on the lineup card today.
  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.
• New York Mets – Moneyline (-110)
  The New York Mets projected batting order ranks as the 3rd-best of all teams today in terms of overall hitting ability.
  Explain: A pitcher who faces a strong opposing offense will be more likely to underperform his usual performance, particularly in terms of hits and runs, in that game.

Washington Nationals Insights

• Cade Cavalli – Over/Under Pitching Outs
  Recording 14 outs per GS this year on average, Cade Cavalli ranks in the 17th percentile.
  Explain: A pitcher who averages more outs per start than his Outs prop may be a good bet to go over, and visa-versa for the under.
• Washington Nationals – 2H Moneyline
  The Washington Nationals bullpen projects as the 5th-worst in baseball, per 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.
