Los Angeles Angels

Seattle Mariners Insights

• Emerson Hancock – Over/Under Strikeouts
  Emerson Hancock has used his four-seam fastball 27.1% more often this season (52.6%) than he did last year (25.5%).
  Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball more often will likely be less effective than he used to be.
• Josh Naylor – Over/Under Stolen Bases
  Josh Naylor’s quickness has declined this year. His 24.42 ft/sec Statcast Sprint Speed last season sits at 21.54 ft/sec now.
  Explain: Slow players tend to get fewer hits because they can’t beat out groundballs, fewer extra base hits, and fewer stolen bases.
• Emerson Hancock – Over/Under Strikeouts
  According to the leading projection system (THE BAT), Cal Raleigh (the Mariners’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).

Los Angeles Angels Insights

• Jack Kochanowicz – Over/Under Strikeouts
  Among all starters, Jack Kochanowicz’s fastball velocity of 94.9 mph grades out in the 75th percentile since the start of last season.
  Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs.
• Josh Lowe – Over/Under Hits
  Based on Statcast metrics, the leading projection system (THE BAT X)’s version of Expected Batting Average (.255) provides evidence that Josh Lowe has had bad variance on his side since the start of last season with his .212 actual batting average.
  Explain: xBA uses highly advanced Statcast data to measure a player’s batting average ability more accurately than actual batting average can.
• Los Angeles Angels – 2H Moneyline
  According to the leading projection system (THE BAT), the Los Angeles Angels’ bullpen projects as the 6th-worst out of all the teams in the game.
  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.
