Tampa Bay Rays

San Francisco Giants Insights

• Robbie Ray – Over/Under 5.5 Strikeouts (+130/-165)
  Robbie Ray has used his slider 9.5% more often this year (32.4%) than he did last season (22.9%).
  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.
• Rafael Devers – Over/Under 0.5 Total Bases (-160/+125)
  Rafael Devers is likely to have an edge against every reliever for the game’s entirety, since the bullpen of the Tampa Bay Rays has just 1 same-handed RP.
  Explain: Hitters perform worse against pitchers of the same handedness (i.e. righty-vs-righty), and being able to avoid those matchups against the bullpen boosts performance and creates hidden edge.
• Robbie Ray – Over/Under 5.5 Strikeouts (+130/-165)
  According to the leading projection system (THE BAT), Patrick Bailey (the Giants’s expected catcher in today’s game) profiles as an elite pitch framer.
  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).

Tampa Bay Rays Insights

• Shane McClanahan – Over/Under 5.5 Strikeouts (+110/-140)
  Shane McClanahan’s 2185-rpm fastball spin rate this year is in the 16th percentile among all starting pitchers.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Yandy Diaz – Over/Under 1.5 Total Bases (+115/-150)
  Hitters such as Yandy Diaz with extreme groundball tendencies are usually more effective when facing pitchers like Robbie Ray who skew towards the flyball end of the spectrum.
  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.
