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.
• Compared to their .334 overall projected rate, the .314 the leading projection system (THE BAT X) wOBA of the Houston Astros projected offense in today’s game suggests this version of the lineup a good deal missing some of their usual firepower.
  Explain: Betting lines are often based on seasonal team quality. If today’s lineup is watered down, however, there may be value if markets aren’t accounting for the lower quality of this offense.
