Arizona Diamondbacks

San Francisco Giants Insights

• Robbie Ray – Over/Under 4.5 Strikeouts (+110/-145)
  Robbie Ray’s slider utilization has increased by 5.8% from last season to this one (22.9% to 28.7%) .
  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.
• Matt Chapman – Over/Under 0.5 Total Bases (-170/+135)
  Today, Matt Chapman is at a disadvantage facing the league’s 3rd-deepest CF center field fences given that he hits his flyballs towards center field at a 38.3% rate (85th 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.

Arizona Diamondbacks Insights

• Zac Gallen – Over/Under 3.5 Strikeouts (-160/+125)
  In his previous start, Zac Gallen didn’t have his best stuff when it came to striking batters out and was only able to tally 2 Ks.
  Explain: A pitcher who struggled in his last outing may have something wrong that affects him in his next outing as well.
• Gabriel Moreno – Over/Under 0.5 Hits (-195/+150)
  Gabriel Moreno has primarily hit in the top-half of the lineup this season (57% of the time), but he is projected to hit 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.
• According to the leading projection system (THE BAT X), the offense with the least strikeout-heavy lineup in today’s games is the Arizona Diamondbacks with a 17.8% underlying K%.
  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.
