St. Louis Cardinals

Kansas City Royals Insights

• Michael Wacha – Over/Under 4.5 Strikeouts (-110/-120)
  Michael Wacha has utilized his slider 5% less often this year (6.9%) than he did last season (11.9%).
  Explain: Because sliders are one of the most effective pitches to use, a pitcher who alters his pitch mix to use them less often may see less success as a result, particularly if he uses his fastball more instead.
• Jac Caglianone – Over/Under 1.5 Total Bases (+140/-185)
  Jac Caglianone hits many of his flyballs to center field (39.2% — 95th percentile) and sets up very well considering he’ll be hitting out towards the game’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.

St. Louis Cardinals Insights

• St. Louis Cardinals – 1st Five Innings (F5) Moneyline (-120)
  In his last GS, Dustin May allowed a whopping 6 earned runs.
  Explain: A pitcher who struggled in his last outing may have something wrong that affects him in his next outing as well.
• Ivan Herrera – Over/Under 1.5 Total Bases (+125/-160)
  Over the past 14 days, Ivan Herrera’s Barrel% has experienced a negative regression, plummeting from his seasonal rate of 6.8% down to 0%.
  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.
• The St. Louis Cardinals have 3 batters in their projected batting order today with a high (i.e. over 27%) underlying K% (according to the leading projection system, THE BAT X) (Pedro Pages, Nolan Gorman, Jordan Walker).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts
