-105O/U: 7.5
(-110/-110)-115

Kansas City Royals – 1st Five Innings (F5) Moneyline (-115)
Considering the 1.35 disparity between Michael Wacha’s 2.69 ERA and his 4.04 FIP, it’s safe to say he’s been one of the luckiest pitchers in the game this year and figures to see worse results in the future.
Explain: Pitchers that are overperforming should be expected to pitch worse going forward, which can create value if the lines are too heavily weighing the lucky, to-date overperformance.
Salvador Perez – Over/Under 1.5 Total Bases (+140/-180)
Salvador Perez has negatively regressed with his Barrel%; his 14.6% rate last year has fallen to 9.1% this year.
Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.
Kansas City Royals – 2H Moneyline
According to the leading projection system (THE BAT), the Kansas City Royals’ bullpen grades out as the 7th-worst out of all the teams in Major League Baseball.
Explain: Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game’s runs.

Jack Leiter – Over/Under 5.5 Strikeouts (+105/-135)
Out of all starters, Jack Leiter’s fastball spin rate of 2449 rpm ranks in the 87th percentile this year.
Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
Joc Pederson – Over/Under 0.5 Hits (-175/+135)
Joc Pederson will probably have the upper hand against every reliever from start to finish, since the bullpen of the Kansas City Royals only has 1 same-handed RP.
Explain: Hitters perform worse against pitchers of the same handedness (i.e. righty-vs-righty), and being able to avoid those matchups against the bullpen boosts performance and creates hidden edge.
Josh Jung – Over/Under 1.5 Total Bases (+140/-180)
Josh Jung hits many of his flyballs to center field (40.1% — 98th percentile) and will be challenged by the game’s 6th-deepest CF fences in today’s matchup.
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.
