San Francisco Giants Insights

• Tyler Mahle – Over/Under 4.5 Strikeouts (-150/+115)
  Tyler Mahle has experienced some positive variance in regards to his strikeouts this year, compiling a 9.07 K/9 despite the leading projection system (THE BAT) estimating his true talent level to be 8.12 — a 0.95 K/9 discrepancy.
  Explain: Pitchers that are overperforming should be expected to pitch worse going forward, which can create value on K prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
• Matt Chapman – Over/Under 0.5 Hits (-195/+150)
  Matt Chapman has primarily hit in the top-half of the lineup this season (88% of the time), but he is penciled in 7th in the batting order today.
  Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
• San Francisco Giants – 2H Moneyline
  According to the leading projection system (THE BAT), the San Francisco Giants’ bullpen projects as the 4th-worst among all the teams in the league.
  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.

Athletics Insights

• Aaron Civale – Over/Under 4.5 Strikeouts (+125/-165)
  Out of all starting pitchers, Aaron Civale’s fastball spin rate of 2430.3 rpm ranks in the 84th percentile since the start of last season.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Darell Hernaiz – Over/Under 0.5 Total Bases (-160/+125)
  Darell Hernaiz’s average exit velocity has declined recently; his 81.9-mph seasonal figure has decreased to 72.3-mph over the last 14 days.
  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.
• Nick Kurtz – Over/Under 1.5 Total Bases (+100/-130)
  Nick Kurtz has a 93rd percentile opposite-field rate on his flyballs (36.8%) and will have to hit them out towards the league’s 6th-deepest LF fences in today’s game.
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.
