+180O/U: 7
(+100/-120)-210

Landen Roupp – Over/Under 15.5 Pitching Outs (-115/-115)
Compared to average, Landen Roupp has been given more leash than the average pitcher this year, tallying an additional 4.6 adjusted pitches each outing.
Explain: Pitchers with a longer leash are more likely to go deeper into games and record more outs.
Drew Gilbert – Over/Under 0.5 Hits (-150/+120)
Drew Gilbert is penciled in 1st on the lineup card today, which would be an upgrade from his 97% rate of hitting in the bottom-half of the batting order 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.
Rafael Devers – Over/Under 0.5 Total Bases (-150/+115)
Rafael Devers has an 87th percentile opposite-field rate on his flyballs (35.1%) and is a great match for the park considering he’ll be hitting them towards the game’s 3rd-shallowest LF fences in today’s game.
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.

Gavin Williams – Over/Under 7.5 Strikeouts (-110/-120)
Gavin Williams has utilized his slider 9.1% more often this year (28.8%) than he did last season (19.7%).
Explain: Because sliders are one of the most effective pitches to use, a pitcher who alters his pitch mix to use more of them will often see more success as a result.
Steven Kwan – Over/Under 1.5 Total Bases (+135/-180)
Steven Kwan’s average exit velocity has fallen off this year; his 86.3-mph EV last season has dropped off to 83.5-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.
Gavin Williams – Over/Under 7.5 Strikeouts (-110/-120)
Projected catcher Patrick Bailey profiles as an elite pitch framer, according to the leading projection system (THE BAT).
Explain: Pitch framing is a catcher’s ability to make a ball look like a strike to the umpire, “stealing” strikes for his pitcher. This leads to more positive outcomes (like strikeouts) and fewer negative ones (like walks or earned runs).
