+110O/U: 7.5
(+100/-120)-130

Joey Cantillo – Over/Under 5.5 Strikeouts (+120/-150)
Out of all starting pitchers, Joey Cantillo’s fastball spin rate of 1873 rpm ranks in the 1st percentile this year.
Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
Steven Kwan – Over/Under 0.5 Total Bases (-170/+130)
Steven Kwan’s average exit velocity has fallen off this year; his 86.3-mph mark last year has fallen off to 82-mph.
Explain: Hitting the ball hard increases the chances of either a home run or the ball landing in fair territory for a hit before a fielder can get to it.
Jose Ramirez – Over/Under 1.5 Total Bases (+125/-160)
Jose Ramirez pulls a high percentage of his flyballs (42.9% — 100th percentile) and will have to hit them out towards the game’s 10th-deepest RF fences in today’s game.
Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.

Detroit Tigers – 1st Five Innings (F5) Moneyline (-140)
The leading projection system (THE BAT X) projects that Casey Mize will concede an average of 2.01 earned runs in today’s matchup.
Explain: THE BAT X is a highly sophisticated projection system that accounts for a multitude of factors like ballpark, weather, umpire, defense, and more.
Wenceel Perez – Over/Under 0.5 Total Bases (-150/+115)
Wenceel Perez has been unlucky this year, compiling a .212 wOBA despite the leading projection system (THE BAT X) estimating his true talent level to be .305 — a .093 difference.
Explain: Players that are underperforming should be expected to play worse going forward, which can create value on prop Overs if the lines are too heavily weighing the unlucky, to-date underperformance.
According to the leading projection system (THE BAT X), the team with the 4th-most strikeout-prone lineup today is the Detroit Tigers with a 24.2% underlying K%.
Explain: THE BAT X analyzes each player in today’s specific lineup to figure out which teams have the most inherent strikeout potential for the opposing pitcher.
