St. Louis Cardinals Insights

• Matthew Liberatore – Over/Under 4.5 Strikeouts (+130/-165)
  Over his previous 3 games started, Matthew Liberatore has suffered a big fall off in his fastball spin rate: from 2076 rpm over the whole season to 1999 rpm in recent games.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs, so a pitcher who improves his spin rate will likely see improved results.
• Jordan Walker – Over/Under 1.5 Total Bases (+130/-170)
  The leading projection system (THE BAT X) estimates Jordan Walker’s true offensive skill to be a .328, implying that he has experienced some positive variance this year given the .115 difference between that figure and his actual .443 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.
• St. Louis Cardinals – 2H Moneyline
  The St. Louis Cardinals bullpen projects as the 6th-best in MLB, 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

• Michael Burrows – Over/Under 16.5 Pitching Outs (-115/-115)
  Compared to the average hurler, Mike Burrows has been given less leash than the typical pitcher since the start of last season, recording an -13.1 fewer adjusted pitches each start.
  Explain: Pitchers with a shorter leash are more likely to get pulled earlier in games and record fewer outs.
• Isaac Paredes – Over/Under 0.5 Total Bases (-165/+130)
  Isaac Paredes has negatively regressed with his Barrel%; his 5.8% rate last year has decreased to 0% this season.
  Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.
• Jose Altuve – Over/Under 1.5 Total Bases (+120/-150)
  Jose Altuve pulls a lot of his flyballs (43.1% — 100th percentile) and sets up very well considering he’ll be hitting them towards MLB’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.
