Reds vs Cardinals Prediction 20 August 2026
📡 The five-game series in Cincinnati wraps up with a daytime clash following yet another nail-biter. On Wednesday, the Reds edged out a 5-4 win, despite St. Louis rallying for two runs in the ninth and nearly pulling off another comeback. After four games, the series is tied at 2-2. Michael McGreevy and Brady Singer are set to start the decisive matchup, with the visitors holding the edge in the pitching duel based on season stats.
Head-to-Head
📊 Over their last 10 head-to-head matchups, St. Louis hold a 6-4 edge. The Cardinals have taken three out of five meetings in August, including both games of the August 17 doubleheader, and this ongoing series has consistently been decided by the slimmest of margins. The last five contests finished 2-1, 5-6, 3-0, 4-5, plus another tightly contested game in the current series, so the slight advantage for the visitors in the H2H stats hardly looks like a fluke.
Head-to-head statistics Reds - Cardinals

Cincinnati Reds Team Overview
The Reds enter the series finale with a 62-66 record after yesterday’s win. Their offense bounced back following Tuesday’s shutout loss, but they had to withstand some late pressure from the Cardinals to secure the result. Over the past four days, the team have played four games, including a doubleheader, which has put a heavy workload on their pitching staff. This could be especially significant if Singer makes a short outing.

St. Louis Cardinals Team Overview
The Cardinals stand at 65-64 and, even after yesterday’s loss, continue to show impressive resilience. Jordan Walker blasted a two-run homer, while JJ Wetherholt reached base twice with hits. St. Louis have taken six of their last eight games heading into Wednesday, and in this series, they have already held Cincinnati to just one run or shut them out entirely on two occasions.

⚾ Starting Pitchers
Michael McGreevy takes the mound for St. Louis, carrying a 4-9 record with a 3.59 ERA and a 1.20 WHIP. Over 120.1 innings, he’s issued just 30 walks, rarely gifting opponents extra chances. While his win-loss tally doesn’t reflect the quality of his pitching, McGreevy’s command is especially valuable against a Cincinnati lineup that thrives on capitalizing when given free passes.
Brady Singer enters with a 5-10 record, a 4.67 ERA, and a 1.43 WHIP. In 113.2 innings, he’s allowed significantly more baserunners than McGreevy. With the hosts already stretching their bullpen over four games in three days, an early exit from Singer would only add to the relievers’ workload.
⭐ Editor's Pick
The teams are meeting for the fifth time in just four days, making the quality and length of today's starting pitching especially crucial. St. Louis have the edge here: McGreevy holds a clear advantage over Singer in both ERA and WHIP, and he issues walks far less frequently. The Cardinals also lead the head-to-head 6-4 over the last 10 matchups, and even after a rough start yesterday, they mounted a serious threat in the ninth inning. The main concern is the accumulated workload on the visitors’ bullpen after this long series. Still, with a more reliable starting pitcher matchup and comparable offenses, St. Louis remain favorites. Our pick: St. Louis Cardinals to win.
