Washington Nationals

St. Louis Cardinals

Washington Nationals Insights

• Andrew Alvarez – Over/Under 14.5 Pitching Outs (-135/+105)
  Andrew Alvarez has been given less leash than the typical pitcher this year, throwing 7.5 fewer adjusted pitches-per-game than the average pitcher.
  Explain: Pitchers with a shorter leash are more likely to get pulled earlier in games and record fewer outs.
• Abimelec Ortiz – Over/Under 0.5 Total Bases (-180/+140)
  Abimelec Ortiz has been hot recently, raising his seasonal exit velocity of 89.7-mph to 98.5-mph in the last 7 days.
  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 batters as a group rank 3rd- in the league for power this year when assessing with their 9% Barrel%.
  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.

St. Louis Cardinals Insights

• Michael McGreevy – Over/Under 3.5 Strikeouts (-140/+110)
  Michael McGreevy’s higher utilization rate of his secondary pitches this season (58.8% vs. 53.1% last season) should work in his favor considering they are generally much more effective than fastballs.
  Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
• Ivan Herrera – Over/Under 1.5 Total Bases (+140/-180)
  Typically, hitters like Ivan Herrera who hit a lot of flyballs generally hit worse when facing pitchers who also induce a lot of flyballs such as Andrew Alvarez.
  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.
• Jordan Walker – Over/Under 1.5 Total Bases (+120/-150)
  Jordan Walker hits a lot of his flyballs to center field (40.3% — 99th percentile) and will have a big advantage facing baseball’s 7th-shallowest CF 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.
