+150O/U: 7.5
(-110/-110)-170

Jacob Lopez – Over/Under 5.5 Strikeouts (-105/-125)
Considering that flyball pitchers have a big advantage over flyball hitters, Jacob Lopez and his 40.7% underlying FB% (according to the leading projection system, THE BAT) finds himself in a favorable position in this game matching up with 2 opposing FB hitters.
Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create boosted performance across all categories and hidden value few are considering.
Carlos Cortes – Over/Under 0.5 Hits (-170/+130)
Carlos Cortes is projected to hit 3rd in the lineup in this game, which would be an upgrade from his 77% rate of hitting in the bottom-half of the lineup this season.
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.
Lawrence Butler – Over/Under 0.5 Total Bases (-125/-105)
Lawrence Butler has a 95th percentile opposite-field rate on his flyballs (37.4%) and will have a big advantage hitting them in the direction of the game’s 9th-shallowest LF 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.

Luis Castillo – Over/Under 5.5 Strikeouts (-120/-110)
It may come as a surprise, but fastballs are generally a pitcher’s least effective pitch. Luis Castillo has utilized his secondary offerings 6.8% more often this year (38.6%) than he did last season (31.8%).
Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
Cal Raleigh – Over/Under 0.5 Total Bases (-135/+105)
Cal Raleigh’s average exit velocity has fallen off this season; his 90.8-mph mark last year has decreased to 84.5-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.
It may be smart to expect better results for the Seattle Mariners offense in future games, given that the leading projection system (THE BAT X) sees them as the 10th-unluckiest offense in the league this year.
Explain: When teams underperform their projected talent level, markets may undervalue them even while they are likely to perform better in the near future.
