St. Louis Cardinals Insights

• Andre Pallante – Over/Under 16.5 Pitching Outs (-105/-125)
  The leading projection system (THE BAT X) expects Andre Pallante to have a pitch count 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.
• Jordan Walker – Over/Under 1.5 Total Bases (+135/-175)
  Jordan Walker has seen a significant gain in his exit velocity this season; just compare his 95.3-mph average to last season’s 92.3-mph mark.
  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.
• St. Louis Cardinals – 2H Moneyline
  The St. Louis Cardinals bullpen ranks as the 6th-best in baseball, according to the leading projection system (THE BAT).
  Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.

Houston Astros Insights

• Lance McCullers Jr. – Over/Under 4.5 Strikeouts (-145/+110)
  Lance McCullers Jr. has utilized his cutter 26.9% more often this year (31.5%) than he did last season (4.6%).
  Explain: Because cutters 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.
• Nick Allen – Over/Under 0.5 Total Bases (-130/+100)
  Typically, bats like Nick Allen who hit a lot of groundballs are generally less successful when facing pitchers who also induce a lot of groundballs such as Andre Pallante.
  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.
• Jose Altuve – Over/Under 1.5 Total Bases (+115/-150)
  Jose Altuve pulls many of his flyballs (43% — 100th percentile) and sets up very well considering he’ll be hitting them towards the league’s 2nd-shallowest LF fences today.
  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.
