Athletics

Seattle Mariners Insights

• Logan Gilbert – Over/Under 5.5 Strikeouts (-145/+115)
  Despite conventional wisdom, fastballs are generally a pitcher’s least effective pitch. Logan Gilbert has used his off-speed and breaking balls 5.8% more often this season (68.1%) than he did last season (62.3%).
  Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
• Randy Arozarena – Over/Under 1.5 Total Bases (+115/-145)
  Randy Arozarena has seen a substantial increase in his exit velocity recently; just compare his 94.6-mph average over the last week to his seasonal 91-mph figure.
  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.
• As a team, Seattle Mariners batters have shined in regard to hitting balls in the launch angle range that tends to result the most in home runs (between 23° and 34°), ranking 6th-best in the game.
  Explain: Balls that are hit too low can’t clear the fences, and balls that are hit too high generally don’t go far enough and are easy pop flies, but balls hit between 23° and 34° are far more likely to become home runs.

Athletics Insights

• Jeffrey Springs – Over/Under 4.5 Strikeouts (+110/-145)
  Jeffrey Springs’s 90.7-mph fastball velocity this year is in the 6th percentile out of all starters.
  Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs.
• Carlos Cortes – Over/Under 1.5 Total Bases (+125/-165)
  The leading projection system (THE BAT X) estimates Carlos Cortes’s true offensive ability to be a .313, suggesting that he has had some very good luck this year given the .098 difference between that mark and his actual .411 wOBA.
  Explain: Players that are overperforming should be expected to play worse going forward, which can create value on prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
• Athletics – 2H Moneyline
  According to the leading projection system (THE BAT), the Athletics’ bullpen projects as the 5th-worst out of 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.
