Houston Astros

Miami Marlins Insights

• Miami Marlins – 1st Five Innings (F5) Moneyline (+100)
  In his last outing, Tyler Phillips was on point and allowed 0 ER.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Heriberto Hernandez – Over/Under 0.5 Hits (-165/+130)
  Heriberto Hernandez is projected to hit 6th in the batting order in this matchup, which would be a downgrade from his 69% 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.
• It may be best to expect worse results for the Miami Marlins offense going forward, considering that the leading projection system (THE BAT X) believes they are the 3rd-luckiest offense in baseball this year.
  Explain: When teams overperform their projected talent level, markets may overvalue them even while they are likely to perform worse in the near future.

Houston Astros Insights

• Tatsuya Imai – Over/Under Pitching Outs
  Compared to league average, Tatsuya Imai has been granted an above-average leash this year, throwing an additional 4.3 adjusted pitches each outing.
  Explain: Pitchers with a longer leash are more likely to go deeper into games and record more outs.
• Jeremy Pena – Over/Under 1.5 Total Bases (+125/-160)
  Jeremy Pena’s exit velocity on flyballs has dropped off this year; his 91.4-mph figure last year has dropped to 87.8-mph.
  Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
• Houston Astros – 2H Moneyline
  The Houston Astros bullpen grades out as the 4th-best in the league, via the leading projection system (THE BAT).
  Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.
