San Francisco Giants Insights

• San Francisco Giants – 1st Five Innings (F5) Moneyline (-110)
  Adrian Houser performed well in his last game started and gave up 1 ER.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Rafael Devers – Over/Under 1.5 Total Bases (+120/-150)
  Rafael Devers has seen a significant gain in his exit velocity recently; just compare his 94.1-mph average in the past week’s worth of games to his seasonal 90.8-mph EV.
  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.
• Heliot Ramos – Over/Under 1.5 Total Bases (+135/-170)
  Heliot Ramos has a 90th percentile opposite-field rate on his flyballs (35.7%) and will have a big advantage hitting them in the direction of the game’s 9th-shallowest RF 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.

Washington Nationals Insights

• Cade Cavalli – Over/Under 15.5 Pitching Outs (+130/-170)
  The leading projection system (THE BAT X) expects Cade Cavalli to be on a bit of a short leash in this game, projecting a maximum of 80 pitches.
  Explain: A pitcher who is on a pitch count is likely to be pulled from the game earlier, record fewer outs, and generate fewer strikeouts.
• Luis Garcia – Over/Under 1.5 Total Bases (+110/-140)
  Extreme flyball hitters like Luis Garcia Jr. usually hit worse against extreme flyball pitchers like Adrian Houser.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create diminished performance across all categories and hidden value few are considering.
• According to the leading projection system (THE BAT X), the projected batting order for the Washington Nationals in today’s game holds an estimated true talent wOBA of .303, which is a fair amount lower than their actual wOBA of .328 this year.
  Explain: Betting lines are often based on seasonal team quality. If today’s lineup is watered down, however, there may be value if markets aren’t accounting for the lower quality of this offense.
