Houston Astros Insights

• Houston Astros – Moneyline (+145)
  The Houston Astros outfield defense profiles as the 2nd-strongest among every team on the slate today.
  Explain: Defense is an integral part of preventing hits and runs.
• Jeremy Pena – Over/Under Total Bases
  Jeremy Pena’s exit velocity on flyballs has decreased this season; his 91.4-mph figure last season has fallen off to 86.6-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.
• Jose Altuve – Over/Under 1.5 Total Bases (+150/-195)
  Jose Altuve pulls many of his flyballs (42.7% — 100th percentile) and sets up very well considering he’ll be hitting them towards MLB’s 8th-shallowest LF fences in today’s game.
  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.

Seattle Mariners Insights

• George Kirby – Over/Under 17.5 Pitching Outs (-170/+130)
  Tallying 92.9 adjusted pitches per outing since the start of last season on average, George Kirby falls in the 83rd percentile.
  Explain: Pitchers who average more pitches per game are more likely to go deeper into games and record more outs.
• Cal Raleigh – Over/Under 1.5 Total Bases (+125/-160)
  Cal Raleigh is an extreme flyball batter and squares off against the strong outfield defense of Houston (#2-best of all teams on the slate today).
  Explain: This player’s skill set matches up poorly with the opposing team’s defensive strength, which may lead to worse-than-usual performance.
• George Kirby – Over/Under 5.5 Strikeouts (-105/-125)
  Projected catcher Cal Raleigh profiles as an elite pitch framer, via the leading projection system (THE BAT).
  Explain: Pitch framing is a catcher’s ability to make a ball look like a strike to the umpire, “stealing” strikes for his pitcher. This leads to more positive outcomes (like strikeouts) and fewer negative ones (like walks or earned runs).
