Kansas City Royals Insights

• Michael Wacha – Over/Under 17.5 Pitching Outs (-170/+135)
  Michael Wacha has been given a longer leash than the average pitcher this year, tallying 5.0 more adjusted pitches-per-game than average.
  Explain: Pitchers with a longer leash are more likely to go deeper into games and record more outs.
• John Rave – Over/Under Total Bases
  In the last 14 days, John Rave’s Barrel% has experienced a negative regression, plummeting from his seasonal rate of 10.4% 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.
• Michael Massey – Over/Under 0.5 Total Bases (-145/+115)
  In today’s game, Michael Massey is at a disadvantage facing the league’s 9th-deepest RF fences given that he hits his flyballs to the pull field at a 38.4% rate (95th percentile).
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.

Houston Astros Insights

• Hunter Brown – Over/Under 5.5 Strikeouts (-135/+105)
  Hunter Brown’s sinker percentage has jumped by 6.2% from last season to this one (23.6% to 29.8%) .
  Explain: Sinkers are the easiest pitches to hit and generate the fewest strikeouts, so a pitcher who begins to use his sinker more often will likely be less effective than he used to be.
• Yainer Diaz – Over/Under 1.5 Total Bases (+135/-170)
  Yainer Diaz has seen a notable improvement in his exit velocity lately; just compare his 96.3-mph average in the past two weeks’ worth of games to his seasonal 89-mph figure.
  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.
• Houston Astros – Moneyline (-160)
  The 3rd-best projected offense on the slate in terms of overall offensive ability is that of the Houston Astros.
  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.
