Toronto Blue Jays Insights

• Shane Bieber – Over/Under 5.5 Strikeouts (+120/-155)
  With 7 batters of the opposite hand in the opposing team’s projected offense, Shane Bieber meets a tough challenge while lacking the platoon advantage in most plate appearances in this matchup.
  Explain: Right-handed pitchers perform worse against left-handed hitters (and visa-versa). If several hitters hold this advantage against the pitcher, it can have a huge impact on whether he will perform well or struggle on any given day.
• Vladimir Guerrero Jr – Over/Under 0.5 Hits (-265/+195)
  When estimating his batting average ability, Vladimir Guerrero Jr. is projected as the 3rd-best batter in the game by the leading projection system (THE BAT X).
  Explain: THE BAT X is a highly sophisticated projection system that accounts for a multitude of factors and regularly tests among the most accurate systems available. Batting average is the most common measure of a player’s ability to generate hits.
• Alejandro Kirk – Over/Under Total Bases
  Alejandro Kirk has a 96th percentile opposite-field rate on his flyballs (37.5%) and has the good fortune of hitting them out towards MLB’s 4th-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.

Seattle Mariners Insights

• Logan Gilbert – Over/Under 5.5 Strikeouts (-105/-125)
  Out of all starters, Logan Gilbert’s fastball spin rate of 2180 rpm grades out in the 14th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Dominic Canzone – Over/Under 0.5 Hits (-225/+170)
  Dominic Canzone has primarily hit in the back-half of the lineup this season (96% of the time), but he is penciled in 3rd in the lineup 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.
• Logan Gilbert – Over/Under 5.5 Strikeouts (-105/-125)
  According to the leading projection system (THE BAT), Cal Raleigh (the Mariners’s expected catcher in today’s game) profiles as an elite pitch framer.
  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).
