Boston Red Sox

Seattle Mariners Insights

• Cal Raleigh – Over/Under 0.5 Total Bases (-125/-105)
  Extreme groundball bats like Cal Raleigh tend to perform worse against extreme groundball pitchers like Payton Tolle.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create diminished performance across all categories and hidden value few are considering.
• Cal Raleigh – Over/Under 0.5 Total Bases (-125/-105)
  Cal Raleigh pulls a lot of his flyballs (43.8% — 100th percentile) and is a great match for the park considering he’ll be hitting them towards baseball’s shallowest LF fences today.
  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.

Boston Red Sox Insights

• Boston Red Sox – Moneyline (-155)
  The Boston Red Sox outfield defense projects as the strongest among all the teams on the slate today.
  Explain: Defense is an integral part of preventing hits and runs.
• Trevor Story – Over/Under 0.5 Hits (-180/+140)
  Trevor Story is penciled in 8th in the lineup in today’s game, which would be a downgrade from his 78% rate of hitting in the top-half of the batting order 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.
• Payton Tolle – Over/Under 6.5 Strikeouts (-110/-120)
  Projected catcher Connor Wong projects as a horrible 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).
