(-110/-110)-125

Luis Gil – Over/Under 4.5 Strikeouts (+110/-140)
Luis Gil’s higher utilization rate of his fastball this season (56.1 compared to 50.6% last year) is not ideal consider they are generally much less effective than breaking or off-speed pitches.
Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball more often will likely be less effective than he used to be.
Amed Rosario – Over/Under 0.5 Hits (-235/+180)
Amed Rosario has primarily hit in the back-half of the lineup this season (50% of the time), but he is projected to hit 1st in the batting order 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.
The 13.4% Barrel% of the New York Yankees makes them the #1 club in the league this year by this standard.
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.

Boston Red Sox – Moneyline (-125)
The Boston Red Sox outfield defense projects as the best out of all the teams today.
Explain: Defense is an integral part of preventing hits and runs.
Willson Contreras – Over/Under 1.5 Total Bases (+135/-175)
Willson Contreras has been hot of late, raising his seasonal exit velocity of 91.9-mph to 101-mph in the past week.
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.
Marcelo Mayer – Over/Under 0.5 Total Bases (-140/+110)
Marcelo Mayer has a 95th percentile opposite-field rate on his flyballs (37.6%) and is a great match for the park considering he’ll be hitting them in the direction of the league’s shallowest LF fences in today’s matchup.
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.
