Both teams played a doubleheader Saturday and both split. St. Louis is 3-7 over their last ten games, averaging just 3.5 runs per game in July. Jordan Walker remains the Cardinals' brightest offensive light, slashing .290/.350/.517 with 22 home runs and an L28d OPS of .893. He is legitimately one of the hotter bats in the National League. The problem is he is 0-for-15 lifetime against Abbott across 15 plate appearances spanning four seasons, posting a 0.200 OPS. Abbott has not just slowed Walker down. He has shut him out completely, and that lefty-righty platoon edge only sharpens the matchup further.

The bullpen picture breaks cleanly in Cincinnati's favor. As one analyst noted this week: "O'Brien has thrown 63 pitches across three recent appearances, while Svanson needed 37 pitches Thursday." Cincinnati's principal relievers Emilio Pagán and Brock Burke both had Thursday off and enter this game fresh. In a tight, low-scoring game, that late-inning depth advantage can decide everything. St. Louis may simply not have the arms to hold a one-run lead if Leahy stumbles early, and based on his history against this lineup, stumbling early is the baseline expectation.

Busch Stadium reinforces the pitching narrative. The park carries a runs factor of 0.98 and a home run factor of 0.95, both slightly suppressing offense. Neither team is running a dominant lineup right now. The Reds post a 4.1 R/G average on the season, while the Cardinals have gone cold in July. Sal Stewart owns Leahy in their limited career matchup (6-for-8, 1.833 OPS), and Nathaniel Lowe has also posted strong numbers against him (1.125 OPS in 8 PA). If Cincinnati gets to Leahy in the middle innings, a depleted St. Louis pen may not have the firepower to respond.

• Kyle Leahy has allowed 12 earned runs in 10 career innings against Cincinnati across three starts. He has never held this lineup under 3 ER in any appearance. That pattern is the foundation of the Reds' edge today.
• Andrew Abbott holds Jordan Walker to .000 AVG and 0.200 OPS across 15 career plate appearances, with declining Walker production in each successive season: 0.000 OPS in 2023, 0.333 in 2024, 0.250 in 2025. The Cardinals' best hitter enters neutralized before the lineup card is posted.
• Masyn Winn is 2-for-17 (.118 AVG, 0.343 OPS) against Abbott with a year-over-year OPS decline: 0.422 in 2024 dropping to 0.250 in 2025. With a L7d OPS of 0.268 on the season, he is in a rough spot facing a lefty who already owns him.
• Sal Stewart is 6-for-8 with a 1.833 OPS against Leahy, including a 1.800 OPS across his five 2026 plate appearances. His 21 HR and .468 slugging percentage suggest the power is live. If Stewart gets good pitches to hit, he will do damage.
• St. Louis's bullpen is stretched thin. Riley O'Brien at 63 pitches across recent outings and Matt Svanson at 37 Thursday means the Cardinals are leaning on lower-leverage arms in a game that figures to be decided late.
• Cincinnati's pen had Thursday off. Pagán and Burke enter fresh in a series where the Cardinals' relievers cannot make the same claim. Bullpen depth is a real tiebreaker in a coin-flip game.

The Under 8.5 at -106 is a lean, not a strong play. Both starters are rested and Busch Stadium suppresses scoring slightly, but the margin is thin. If you are looking to consolidate exposure, the four-leg same-game parlay (Reds ML, Under 8.5, Abbott Over 3.5 Ks, Walker Under 1.5 hits) ties all the key threads together. When Abbott is dealing, the Cardinals' lineup goes quiet, the total stays down, and Cincinnati wins. The legs are correlated by design.

The risk is real. Abbott has walked 50 batters this season, and one crooked inning early could flip the game script entirely. Walker is one of the hottest hitters in the National League, and history means nothing if Abbott's command deserts him in the first three innings. Manage units accordingly and do not oversize a plus-money game bet. For the full slate, see our MLB picks today, NRFI picks, and player props.
