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 25th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Carson Benge – Over/Under 0.5 Hits (-245/+185)
  Carson Benge has primarily hit in the back-half of the lineup this year (66% 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.
• It may be sensible to expect better results for the New York Mets offense in future games, given that the leading projection system (THE BAT X) sees them as the unluckiest offense in the game this year.
  Explain: When teams underperform their projected talent level, markets may undervalue them even while they are likely to perform better in the near future.

Washington Nationals Insights

• Cade Cavalli – Over/Under Pitching Outs
  Recording 14 outs per GS this year on average, Cade Cavalli ranks in the 16th 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.
• James Wood – Over/Under 1.5 Total Bases (+140/-180)
  James Wood has seen a notable improvement in his exit velocity this year; just compare his 96.4-mph average to last season’s 94.3-mph EV.
  Explain: Hitting the ball hard increases the chances of either a home run or the ball landing in fair territory for a hit before a fielder can get to it.
• Washington Nationals – 2H Moneyline
  The Washington Nationals bullpen projects as the 9th-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.
