Baltimore Orioles

Arizona Diamondbacks Insights

• Ryne Nelson – Over/Under 4.5 Strikeouts (-150/+120)
  Ryne Nelson’s slider usage has risen by 7.5% from last year to this one (12.6% to 20.1%) .
  Explain: Because sliders are one of the most effective pitches to use, a pitcher who alters his pitch mix to use more of them will often see more success as a result.
• Ildemaro Vargas – Over/Under Hits
  Ildemaro Vargas has primarily hit in the top-half of the batting order this season (50% of the time), but he is penciled in 7th in the batting order today.
  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.
• Arizona Diamondbacks batters collectively grade out 10th- in the league for power since the start of last season when judging by 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.

Baltimore Orioles Insights

• Colton Cowser – Over/Under 0.5 Total Bases (-140/+110)
  The Arizona Diamondbacks don’t have any same-handed relievers in their bullpen, so Colton Cowser is certain to never face a bullpen mismatch all game.
  Explain: Hitters perform worse against pitchers of the same handedness (i.e. righty-vs-righty), and being able to avoid those matchups against the bullpen boosts performance and creates hidden edge.
• Coby Mayo – Over/Under 0.5 Total Bases (-135/+105)
  Coby Mayo pulls many of his flyballs (37% — 91st percentile) and has the misfortune of hitting them towards baseball’s 4th-deepest LF fences in today’s matchup.
  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.
