St. Louis Cardinals

The St. Louis Cardinals host the Colorado Rockies in the third game of their series on August 13, 2025. Last night, the Rockies shut out the Cardinals with a score of 3-0, further emphasizing the struggles of St. Louis as they attempt to turn the tide on an average season, currently holding a record of 61-60. Meanwhile, the Rockies continue to endure a dismal campaign at 31-88.

In tonight’s matchup, the Cardinals will send Michael McGreevy to the mound, who has shown promise despite his average 4.40 ERA this year. McGreevy’s advanced metrics are encouraging, as he ranks as the 63rd best starting pitcher in MLB according to the leading MLB projection system, suggesting he is likely to improve. His last outing was impressive, as he pitched a complete game shutout on August 8, allowing no earned runs while striking out three.

On the other hand, the Rockies will counter with Austin Gomber, whose record of 0-6 and a troubling ERA of 6.52 reflect a challenging season. Gomber struggled in his latest start, allowing six earned runs over six innings. With the Rockies having one of the worst offenses in MLB, ranking 26th, they face an uphill battle against a Cardinals offense that, while only ranking 19th overall, has the potential for breakout performances.

The Cardinals’ bats, bolstered by their best hitter’s impressive recent form—batting .462 with a 1.346 OPS over the past week—will seek to capitalize on Gomber’s struggles. With the Cardinals as significant betting favorites, their implied team total of 4.78 runs highlights the expectation of a bounce-back performance against a struggling Rockies squad.

Colorado Rockies Insights

• Austin Gomber – Over/Under 3.5 Strikeouts (+115/-145)
  Austin Gomber’s higher usage rate of his secondary pitches this year (66% vs. 59.6% last year) should work in his favor since they are generally much more effective than fastballs.
  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.
• Jordan Beck – Over/Under 1.5 Total Bases (+145/-185)
  Jordan Beck has been lucky this year, putting up a .349 wOBA despite the leading projection system (THE BAT X) estimating his true talent level to be .305 — a .044 deviation.
  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.
• Mickey Moniak – Over/Under 1.5 Total Bases (+120/-155)
  Mickey Moniak pulls a high percentage of his flyballs (34.6% — 87th percentile) and will have to hit them out towards baseball’s 2nd-deepest RF fences in today’s matchup.
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.

St. Louis Cardinals Insights

• Michael McGreevy – Over/Under 4.5 Strikeouts (+125/-160)
  Among all SPs, Michael McGreevy’s fastball velocity of 90.9 mph grades out in the 19th percentile this year.
  Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs.
• Nolan Gorman – Over/Under 0.5 Total Bases (-170/+130)
  Nolan Gorman has big-time HR ability (96th percentile) if he makes contact, but that’s usually a big “IF” (31.3% K%). Today, however, opposing pitcher Austin Gomber doesn’t generate many whiffs (6th percentile K%) — great news for Gorman.
  Explain: If he is less likely to strikeout, he’ll be more likely to make contact, which is often hard, home-run contact.
• The St. Louis Cardinals have 3 bats in their projected lineup today with a high (i.e. over 27%) underlying K% (per the leading projection system, THE BAT X) (Nolan Gorman, Thomas Saggese, Pedro Pages).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts
