Cardinals vs Reds Live: What’s Happening Now, Score, Lineups and What Comes Next?
The Cardinals vs Reds matchup is turning into one of the more interesting MLB searches of the day because St. Louis and Cincinnati are not playing just one game.
They are playing a split doubleheader, creating two games in Cincinnati on Monday, August 17.
The first game began at 1:40 p.m. ET, while the second is scheduled for 6:40 p.m. ET. The doubleheader was created after a previous Cardinals-Reds game was postponed because of rain.
And that changes the entire story.
A normal nine-inning game is already a test of pitching and offense.
A doubleheader can become an 18-inning battle involving starting pitchers, bullpen availability, bench depth and player fatigue.
That’s why the biggest question surrounding Cardinals vs Reds today isn’t simply who has the better record.
It’s:
Which team can survive the entire doubleheader better?
Cardinals vs Reds Live: What Is Happening?
The first game of the Cardinals vs Reds doubleheader is currently underway.
The live game has St. Louis ahead early, with the Cardinals taking a 2–0 lead over Cincinnati in the available live game data.
Because baseball changes quickly, the score can move significantly between updates.
For readers checking Cardinals vs Reds live score, the most important thing is to follow the current inning and not rely on an earlier score appearing in search results or social media.
The first game also matters for the second game.
Every inning can affect how managers use their bullpens.
Why This Cardinals vs Reds Game Matters
The Cardinals entered the matchup at 63–61, while the Reds were 59–64. St. Louis also entered the series with a 5–3 advantage over Cincinnati in their 2026 head-to-head meetings.
That gives the Cardinals vs Reds matchup additional importance.
St. Louis has been playing better recently, while Cincinnati has been trying to stop a difficult stretch.
The Cardinals had won seven of their previous 10 games entering the series, while Cincinnati had lost its previous two games.
For St. Louis, this is an opportunity to continue building momentum.
For Cincinnati, the doubleheader is an opportunity to change the direction of the series quickly.
Why Is Cardinals vs Reds a Doubleheader Today?
This isn’t a random doubleheader.
The teams were originally scheduled to play on May 24, but that game was postponed because of rain.
MLB announced that the postponed contest would be made up as the first game of a split doubleheader on August 17.
The regularly scheduled evening game remained at 6:40 p.m. ET.
That means fans get two separate Cardinals vs Reds games today.
And the second game could look very different from the first.
Cardinals vs Reds Lineups
The lineups are particularly important because managers have to balance today’s two games.
For St. Louis, Joshua Báez, Iván Herrera, Jordan Walker and Alec Burleson are among the key offensive names attracting attention.
For Cincinnati, Elly De La Cruz, Sal Stewart, Tyler Stephenson and Eugenio Suárez are important parts of the offensive attack.
Cardinals players to watch
Joshua Báez
The young Cardinals hitter has quickly become one of the most interesting stories around the team.
Jordan Walker
Walker provides another important power option in the St. Louis lineup.
Alec Burleson
Burleson remains one of the Cardinals’ important middle-of-the-order bats.
Reds players to watch
Elly De La Cruz
De La Cruz can change a game with his combination of speed and power.
Sal Stewart
Stewart has become another important offensive contributor for Cincinnati.
Eugenio Suárez
Suárez gives the Reds another serious power threat.
What Makes the Cardinals vs Reds Doubleheader So Difficult?
The biggest issue is pitching.
A manager doesn’t simply have to ask:
“Who starts today?”
The question becomes:
“Who is available after Game 1?”
If a team uses several important relievers during the opener, those pitchers may not be available—or may be limited—for the night game.
That can completely change the matchup.
The current series preview specifically highlights Cincinnati’s pitching depth as an important concern entering the doubleheader.
Cardinals vs Reds Game 2 Could Be Completely Different
The second Cardinals vs Reds game is scheduled for 6:40 p.m. ET.
St. Louis is expected to have Andre Pallante involved in the second-game pitching plan, while Cincinnati’s pitching situation is subject to the way the first game and bullpen usage develop.
This is why it would be a mistake to treat Game 2 as simply a continuation of Game 1.
If the Cardinals win the opener while using relatively few important relievers, they could enter Game 2 with a significant pitching advantage.
If Cincinnati manages to protect its bullpen, the night game could be much more balanced.
Cardinals vs Reds Prediction: Who Has the Edge?
If you’re searching for a Cardinals vs Reds prediction, there are several reasons to lean toward St. Louis.
The Cardinals entered the series:
- With a better overall record
- With a 5–3 season advantage over Cincinnati
- Coming off a strong stretch of baseball
- With seven wins in their previous 10 games
Cincinnati, meanwhile, entered the matchup at 59–64 and had lost its previous two games.
But baseball is not played on paper.
Great American Ball Park can create high-scoring games, and Cincinnati has enough offensive talent to punish mistakes.
So the smarter prediction is not simply:
“The Cardinals will win.”
The more useful read is:
St. Louis has the stronger overall momentum, but Cincinnati’s offense makes this a dangerous matchup if the Cardinals’ pitching loses control.
Cardinals vs Reds Odds
Current betting markets have generally made St. Louis a slight favorite.
One market had the Cardinals around -120 and Cincinnati around +105, with a total around 9.5 runs for the matchup.
But odds can change quickly.
They can move because of:
- Starting-pitcher confirmation
- Lineup changes
- Bullpen availability
- Injuries
- Betting activity
- Weather
- Game-one results
For that reason, anyone searching for Cardinals vs Reds odds should treat a displayed line as time-sensitive rather than permanent.
What Should Fans Watch During Cardinals vs Reds?
There are five major things to watch.
1. The Cardinals’ Early Offense
If St. Louis scores early, Cincinnati may have to use its bullpen sooner than planned.
That could become extremely important in Game 2.
2. Cincinnati’s Bullpen
This may be the biggest factor of the entire doubleheader.
Every additional reliever used in Game 1 can affect Game 2.
3. Elly De La Cruz
If Cincinnati wants to turn the game around, De La Cruz is one of the players capable of doing it quickly.
4. Jordan Walker and Alec Burleson
The Cardinals need their middle-order hitters to continue creating pressure.
5. Managerial Decisions
Doubleheaders reward managers who can think beyond one game.
A manager may sacrifice a little in Game 1 to protect the bullpen for Game 2—or do the opposite if winning the opener becomes the priority.
What Does Cardinals vs Reds Mean for the NL Central?
The Cardinals vs Reds matchup also matters because both teams are trying to stay relevant in the National League race.
St. Louis entered the day chasing a postseason opportunity, while Cincinnati was sitting at the bottom of the NL Central.
That creates different pressure for each club.
The Cardinals need to turn good recent form into sustained results.
The Reds need to prevent a difficult stretch from becoming a larger problem.
And because this is a doubleheader, the standings could move by two games in a single day.
Cardinals vs Reds: What Happens If the First Game Goes Long?
This is one of the most overlooked parts of today’s matchup.
If Game 1 goes deep into extra innings, both teams could be forced to use more pitchers.
That would make Game 2 much more unpredictable.
A normal game might require a certain number of bullpen arms.
A long first game could dramatically increase that number.
That’s why the final innings of Game 1 could matter even after the first game’s winner is decided.
Cardinals vs Reds Live Updates: What Fans Should Know
If you’re searching Cardinals vs Reds live, don’t just look for the final score.
Look at:
- Current inning
- Pitch count
- Starting pitcher
- Bullpen usage
- Lineup changes
- Injuries
- Game 2 pitching availability
Those details can tell you much more about what is coming next.
For example, if Cincinnati has already used several important relievers, that could become one of the biggest stories heading into the night game.
