Boston Red Sox Insights

• Ranger Suarez – Over/Under 4.5 Strikeouts (-150/+120)
  Given that groundball batters hold a big advantage over flyball pitchers, Ranger Suarez and his 47.2% underlying GB% (according to the leading projection system, THE BAT) will be in a tough position in today’s outing going up against 2 opposing GB bats.
  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.
• Ceddanne Rafaela – Over/Under 0.5 Hits (-225/+170)
  Ceddanne Rafaela has primarily hit in the back-half of the lineup this year (59% of the time), but he is projected to bat 2nd in the batting order today.
  Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
• Carlos Narvaez – Over/Under Total Bases
  Carlos Narvaez has a 94th percentile opposite-field rate on his flyballs (36.8%) and is a great match for the park considering he’ll be hitting them towards the league’s 6th-shallowest RF 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.

Cleveland Guardians Insights

• Tanner Bibee – Over/Under 4.5 Strikeouts (-150/+115)
  Tanner Bibee’s slider percentage has decreased by 13.9% from last year to this one (15.4% to 1.5%) .
  Explain: Because sliders are one of the most effective pitches to use, a pitcher who alters his pitch mix to use them less often may see less success as a result, particularly if he uses his fastball more instead.
• David Fry – Over/Under Total Bases
  David Fry’s exit velocity on flyballs has declined this year; his 93.9-mph mark last season has decreased to 89.3-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.
• Tanner Bibee – Over/Under 4.5 Strikeouts (-150/+115)
  Patrick Bailey, the Guardians’s expected catcher today, projects as an elite pitch framer according to 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).
