+125O/U: 9.5
(-115/-105)-145

Gabriel Hughes – Over/Under 15.5 Pitching Outs (-105/-125)
Gabriel Hughes has been given less leash than the typical pitcher this year, throwing 8.3 fewer adjusted pitches-per-game than average.
Explain: Pitchers with a shorter leash are more likely to get pulled earlier in games and record fewer outs.
T.J. Rumfield – Over/Under 1.5 Total Bases (+135/-170)
The leading projection system (THE BAT X) estimates T.J. Rumfield’s true offensive talent to be a .293, indicating that he has experienced some positive variance this year given the .062 difference between that mark and his actual .355 wOBA.
Explain: Players that are overperforming should be expected to play worse going forward, which can create value on prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
Today’s version of the Rockies projected batting order is missing some of their usual firepower, as their .294 the leading projection system (THE BAT X) wOBA is considerably below their .321 overall projected rate.
Explain: Betting lines are often based on seasonal team quality. If today’s lineup is watered down, however, there may be value if markets aren’t accounting for the lower quality of this offense.

Jake Irvin – Over/Under 4.5 Strikeouts (-105/-125)
Jake Irvin’s curveball rate has fallen by 6.6% from last year to this one (29.9% to 23.3%) .
Explain: Because curveballs 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.
Andrés Chaparro – Over/Under 1.5 Total Bases (+125/-165)
Andres Chaparro has negatively regressed with his Barrel% in recent games; his 14.1% seasonal rate has dropped off to 0% over the last 7 days.
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.
Washington Nationals – 2H Moneyline
The Washington Nationals bullpen profiles as the 7th-worst in the game, according to the leading projection system (THE BAT).
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.
