+120O/U: 7
(-110/-110)-145

Zac Gallen – Over/Under 4.5 Strikeouts (-110/-120)
Zac Gallen’s four-seamer percentage has fallen by 7.9% from last year to this one (45.4% to 37.5%) .
Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball lessoften will likely be more effective than he used to be.
Adrian Del Castillo – Over/Under 0.5 Total Bases (-125/-105)
Adrian Del Castillo is an extreme flyball hitter and squares off against the weak outfield defense of Seattle (#2-worst of all teams on the slate today).
Explain: This player’s skill set matches up well with the opposing team’s defensive weakness, which may lead to better-than-usual performance.
Gabriel Moreno – Over/Under 0.5 Total Bases (-195/+150)
Gabriel Moreno has a 98th percentile opposite-field rate on his flyballs (38.8%) and sets up very well considering he’ll be hitting them towards baseball’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 – Moneyline (-145)
Among all the teams in action today, the 2nd-worst infield defense is that of the Seattle Mariners.
Explain: Defense is an integral part of preventing (or, in this case, allowing) hits and runs.
Cole Young – Over/Under 0.5 Total Bases (-155/+120)
Over the last two weeks, Cole Young’s Barrel% has experienced a negative regression, plummeting from his seasonal rate of 6% down to 0%.
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.
As a team, Seattle Mariners hitters have shined in regard to hitting balls in the launch angle span that tends to optimize home runs (between 23° and 34°), rating 6th-best in the majors.
Explain: Balls that are hit too low can’t clear the fences, and balls that are hit too high generally don’t go far enough and are easy pop flies, but balls hit between 23° and 34° are far more likely to become home runs.
