Arizona Diamondbacks

Chicago White Sox Insights

• Sean Burke – Over/Under 4.5 Strikeouts (+135/-175)
  Sean Burke’s sinker rate has jumped by 8.6% from last season to this one (5% to 13.6%) .
  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.
• Colson Montgomery – Over/Under 0.5 Total Bases (-165/+130)
  Colson Montgomery pulls a lot of his flyballs (40.4% — 98th percentile) and will have to hit them out towards the game’s 3rd-deepest RF fences today.
  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.

Arizona Diamondbacks Insights

• Arizona Diamondbacks – 1st Five Innings (F5) Moneyline (-165)
  Merrill Kelly was firing on all cylinders in his last game started and conceded 2 ER.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Nolan Arenado – Over/Under 0.5 Hits (-195/+150)
  Nolan Arenado is projected to hit 7th in the lineup today, which would be a downgrade from his 50% rate of hitting in the top-half of the batting order this year.
  Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
• The Arizona Diamondbacks (19.6 K% (according to the leading projection system, THE BAT X) are projected to have the 2nd-least strikeout-heavy set of hitters of all teams today.
  Explain: THE BAT X analyzes each player in today’s specific lineup to figure out which teams have the least inherent strikeout potential for the opposing pitcher.
