Seattle Mariners

San Francisco Giants Insights

• Logan Webb – Over/Under 5.5 Strikeouts (-115/-115)
  Out of all SPs, Logan Webb’s fastball spin rate of 2086 rpm is in the 11th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Willy Adames – Over/Under 0.5 Hits (-130/+100)
  Willy Adames has primarily hit in the top-half of the lineup this year (61% of the time), but he is projected to hit 7th in the lineup in this game.
  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.
• The San Francisco Giants have 3 batters in their projected batting order today with a high (i.e. over 27%) underlying K% (according to the leading projection system, THE BAT X) (Bryce Eldridge, Willy Adames, Drew Cavanaugh).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts

Seattle Mariners Insights

• Bryan Woo – Over/Under 17.5 Pitching Outs (-175/+135)
  Bryan Woo has averaged 17.4 outs per outing this year, grading out in the 85th percentile.
  Explain: A pitcher who averages more outs per start than his Outs prop may be a good bet to go over, and visa-versa for the under.
• Dominic Canzone – Over/Under 1.5 Total Bases (+145/-185)
  Dominic Canzone has seen a notable increase in his exit velocity on flyballs this year; just compare his 96.6-mph average to last year’s 94.1-mph EV.
  Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
• Seattle Mariners – 2H Moneyline
  The Seattle Mariners bullpen projects as the 10th-worst in Major League Baseball, according to the leading projection system (THE BAT).
  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.
