Miami Marlins

Arizona Diamondbacks Insights

• Zac Gallen – Over/Under 4.5 Strikeouts (-110/-120)
  Zac Gallen’s four-seamer percentage has dropped by 7.1% from last season to this one (45.4% to 38.3%) .
  Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball lessoften will likely be more effective than he used to be.
• Geraldo Perdomo – Over/Under 0.5 Hits (-155/+120)
  Geraldo Perdomo is penciled in 7th in the batting order in this matchup, which would be a downgrade from his 94% rate of hitting in the top-half of the lineup this season.
  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’s 88.4-mph average exit velocity this year is one of the worst in the league: #24 overall.
  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.

Miami Marlins Insights

• Max Meyer – Over/Under 5.5 Strikeouts (-120/-110)
  Max Meyer’s 2596-rpm fastball spin rate this year ranks in the 99th percentile among all starting pitchers.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Kyle Stowers – Over/Under 1.5 Total Bases (+130/-170)
  Kyle Stowers is apt to have an edge against every reliever throughout the game, since the bullpen of the Arizona Diamondbacks has just 1 same-handed RP.
  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.
• Owen Caissie – Over/Under 0.5 Total Bases (-140/+110)
  Owen Caissie hits a lot of his flyballs to center field (38.9% — 91st percentile) and will have a big advantage facing the league’s 6th-shallowest CF fences in today’s matchup.
  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.
