There’s an electricity to a Cubs-Cardinals game at Busch Stadium that you can almost feel through the screen. It’s a classic, storied rivalry steeped in a century of baseball history. Fans live and breathe it, and the intensity on the field is palpable. But as an analyst, I’ve learned that the most profitable opportunities often arise when you strip away the narrative and let the numbers tell their own story.
I remember a few seasons back, there was a similar high-profile divisional game where one team was a heavy public favorite. The narrative was entirely on their side. But the data whispered a different tale—a starting pitcher whose solid ERA was masking a dangerously high xFIP, and a bullpen that was running on fumes. We faded the public, trusted the underlying metrics, and were rewarded with a comfortable underdog win. It was a perfect reminder that emotion fuels the market, but data builds the foundation for success.
Today, as the Chicago Cubs (-136) visit the St. Louis Cardinals (+114), we have another fascinating puzzle to solve. On the surface, it’s a tight divisional matchup. But beneath the odds, a deeper analysis reveals a potential value play. Let’s shut out the noise and dive into the data.
The Starting Pitcher Duel: A Tale of Two Realities
The outcome of any baseball game so often hinges on the two men standing 60 feet, 6 inches apart. In this matchup, we have a fascinating contrast in pitcher profiles between the Cubs’ Matt Boyd and the Cardinals’ Erick Fedde.
Matt Boyd, Chicago Cubs (LHP)
- 2025 Season Stats (Projected): 4.28 ERA, 1.35 WHIP, 8.5 K/9, 3.2 BB/9
- Advanced Metrics: 4.75 FIP, 4.60 xFIP, 4.45 SIERA
At first glance, Matt Boyd’s 4.28 ERA seems serviceable for a back-of-the-rotation starter. However, this is where we need to look under the hood. His advanced metrics are flashing significant warning signs. A FIP (Fielding Independent Pitching) of 4.75, nearly half a run higher than his ERA, tells us he’s been the beneficiary of some good fortune on balls in play. His xFIP and SIERA, which normalize for league-average results, both sit in the mid-4.00s, suggesting he is, at best, a league-average arm who has been pitching slightly over his head.
Boyd’s primary issue is his tendency to give up hard contact and home runs, a persistent trait throughout his career. He’s a fly-ball pitcher, and on a warm, humid day at Busch Stadium, that can be a recipe for disaster. While he can miss bats at a decent clip, his command can be spotty, leading to walks that often come back to haunt him via the long ball.
Erick Fedde, St. Louis Cardinals (RHP)
- 2025 Season Stats (Projected): 3.65 ERA, 1.22 WHIP, 7.8 K/9, 2.8 BB/9
- Advanced Metrics: 3.80 FIP, 3.95 xFIP, 4.05 SIERA
Erick Fedde presents a much different and, frankly, more encouraging profile. After a transformative stint in the KBO where he reinvented his arsenal, Fedde has returned to the MLB as a more effective pitcher. His success is built on a high ground-ball rate, a direct result of his improved sinker and sweeper combination.
Unlike Boyd, Fedde’s advanced numbers support his solid ERA. His FIP of 3.80 is right in line with his performance, indicating that his success is sustainable and earned. He doesn’t rely on strikeouts as much as Boyd does, but he excels at inducing weak contact and letting his defense work for him. This is a crucial advantage, as it limits the potential for multi-run innings fueled by home runs. He keeps the ball in the park, a skill that provides a high floor of performance in any given start.
Pitching Edge: This is a clear advantage for the St. Louis Cardinals. Fedde’s underlying metrics are stronger, his profile as a ground-ball pitcher is more stable, and he is less prone to the catastrophic inning that can derail a game.
Analyzing the Offenses and Defensive Support
While pitching is critical, the lineups and the fielders behind them will shape this contest.
Offensive firepower: The Cubs and Cardinals offenses are surprisingly similar on paper. Chicago holds a slight edge in wRC+ (Weighted Runs Created Plus), sitting around 104 for the season, meaning they are about 4% better than the league-average offense. The Cardinals are right at league average with a 100 wRC+.
However, recent trends are important. The Cubs have been reliant on the power of hitters like Christopher Morel and Seiya Suzuki, but have been prone to streakiness. The Cardinals, led by the consistent Paul Goldschmidt and Nolan Arenado, have a more contact-oriented approach that can be effective at manufacturing runs, especially against pitchers like Boyd who can be wild.
Bullpen Strength: The bullpens present another area of contrast. The Cubs’ relief corps has been a source of frustration this season, marred by injuries to key setup men like Javier Assad and Ben Heller. Their middle relief has been inconsistent, often struggling to hold leads.
The Cardinals, meanwhile, boast a deeper and more reliable bullpen anchored by closer Ryan Helsley. Their ability to shorten the game gives them a significant advantage if they can get a lead into the later innings. If this turns into a battle of relievers, St. Louis has the upper hand.
Defense: Defensively, St. Louis is the superior team. With Gold Glove-caliber players like Nolan Arenado at third base and a solid defensive outfield, they are well-equipped to support a ground-ball pitcher like Fedde. The Cubs’ defense is average at best, which could further expose Boyd’s tendency to allow balls in play.
Environmental and Situational Factors
- Ballpark & Weather: Busch Stadium is generally considered a neutral park, but it can play smaller during the humid summer months. Today’s forecast calls for temperatures in the high 80s with moderate humidity and a slight breeze blowing out to left field. This weather slightly favors the hitters and increases the risk for a fly-ball pitcher like Boyd.
- Injuries: Chicago’s pitching depth is being tested. The absences of Shota Imanaga and Justin Steele from the rotation, and key bullpen arms, put more pressure on the remaining staff. For St. Louis, the loss of catcher Ivan Herrera hurts, but their core lineup remains intact.
- Recent Form: Both teams have been treading water lately, playing around .500 baseball over their last 15 games. Neither team enters with overwhelming momentum, making this a classic “get right” spot for the victor.
Synthesizing the Data with Prediction Models
Before making a final call, I always cross-reference my analysis with leading industry projection models.
- FanGraphs: Projects a close game, but leans slightly towards the Cardinals due to the pitching mismatch.
- Baseball Prospectus (PECOTA): Sees this as a near toss-up, with a slight edge to the home team.
- FiveThirtyEight: Their model likely favors the Cubs slightly due to their marginally better overall season metrics, but this can often overlook the nuance of a specific pitching matchup.
- The Action Network & Massey Ratings: Projections from these betting-focused models are likely to align more closely with my analysis, recognizing Fedde as the superior starter in this contest and flagging the Cardinals as a live underdog.
The consensus is that this is a tight game, but the models that weigh starting pitching heavily are pointing towards value on the home team.
The Final Verdict and Recommended Bet
After a thorough breakdown of every conceivable angle, the path to value becomes clear. The market has made the Cubs a road favorite based on their slightly better season-long offensive numbers, but it’s undervaluing the most critical factor in this specific game: the disparity on the mound.
Erick Fedde’s sustainable, ground-ball-inducing profile is a direct counter to the Cubs’ inconsistent offense and is perfectly suited for the conditions at Busch Stadium. Matt Boyd, conversely, is a regression candidate whose fly-ball tendencies are a major liability against a Cardinals lineup capable of capitalizing on mistakes. Combined with a superior bullpen and defense, the Cardinals have multiple paths to victory.
PICK: Total Points OVER 9
Reasoning: This price offers significant value. In my view, the Cardinals should be slight favorites in this game, not underdogs. We are backing the better starting pitcher, the more reliable bullpen, and the stronger defensive team, all at a plus-money price. This is a classic case of fading a team with underlying negative indicators (Boyd) in favor of one with a more stable foundation (Fedde).
- Value Player Prop: Erick Fedde Over 4.5 Strikeouts. The Cubs have several high-strikeout hitters in their lineup. While Fedde isn’t a strikeout artist, he is efficient, and this number is low enough for him to clear by the sixth inning.
This game won’t be decided by the historical rivalry, but by the fundamental advantages St. Louis holds in pitching and defense. It’s a prime example of why a deep, data-first approach is so crucial. By looking past the surface-level narratives, we uncover the true value propositions that lead to long-term success.
