Washington Nationals Insights

• Jake Irvin – Over/Under 3.5 Strikeouts (-130/+100)
  In his last start, Jake Irvin performed well and compiled 7 strikeouts.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Andrés Chaparro – Over/Under 0.5 Total Bases (-165/+130)
  Despite posting a .377 wOBA this year, the leading projection system (THE BAT X) believes Andres Chaparro has been lucky given the .062 difference between that mark and his estimated true talent wOBA of .315.
  Explain: Players that are overperforming should be expected to play worse going forward, which can create value on prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
• The 9% Barrel% of the Washington Nationals ranks them as the #3 squad in baseball this year by this metric.
  Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.

  Quinn Mathews has been given a shorter leash than the typical pitcher this year, throwing 7.1 fewer adjusted pitches-per-game than average.

• Jordan Walker – Over/Under 1.5 Total Bases (+130/-170)
  Jordan Walker hits a lot of his flyballs to center field (40.3% — 98th percentile) and will have a big advantage facing baseball’s 7th-shallowest CF fences in today’s game.
