The final day of the 2026 MLB regular season has arrived, and two wild-card races are on the line today. The Houston Astros need a win to clinch the AL West title and an AL Wild Card spot over the Texas Rangers, while the Arizona Diamondbacks can clinch the third NL Wild Card spot with a win and a Philadelphia Phillies loss to the Tampa Bay Rays. Both games air at 3pm ET, and fans can watch on Peacock and NBCSN.
The Astros and Athletics at Sutter Health Park
Houston takes on the Athletics at 3pm ET on Sunday, September 27. The game airs on NBCSN, with a live stream available on Peacock. Home and away feeds are available through the streaming service.
A win for the Astros clinches the AL West. It also secures an AL Wild Card spot over the Rangers, who would be eliminated if Houston wins and the Astros hold their edge in the standings. The stakes are simple: win, advance. Lose, and the Rangers keep the door open.
The Diamondbacks and Padres at Petco Park
At the same time, the Arizona Diamondbacks face the San Diego Padres at Petco Park. Arizona can clinch the third NL Wild Card spot with a win, provided the Phillies lose to the Rays. That means two games, two outcomes, and only one combination gets Arizona in.
The Diamondbacks game also airs on Peacock, with a live stream available alongside the TV broadcast. Home and away feeds are available through the streaming service.
Devices and Platforms for Watching
Peacock is the primary streaming home for both games. The service offers home and away feeds, meaning viewers can switch between the two broadcasts during the game. That matters for fans who want to see the Astros and the Diamondbacks in the same day.
Peacock is available across a variety of devices. Viewers can check the full list of supported devices to see what works for them. The platform carries both games, so a single subscription covers both broadcasts.
NBCSN is also carrying the Astros game. The network is available on YouTube TV, Fubo and Xfinity. Those options give cord-cutters a path to the broadcast beyond Peacock, though Peacock remains the simplest route for both games.
What Happens After Today
The 2026 MLB postseason starts with the Wild Card Round from September 29 to October 1. That round is available exclusively on NBC, Peacock and NBCSN.
Fans who want to follow the entire postseason should plan around those networks. Peacock subscribers will have access to Wild Card games on the service, with NBCSN also carrying the broadcasts. The three networks share the load for the early rounds.
Signing Up for Peacock
New viewers can sign up for Peacock to watch the games today. The service offers a range of pricing options, though the source does not specify the cost of a subscription. Fans who already have Peacock do not need a separate login for the broadcasts.
The service requires a working internet connection to stream. Home and away feeds are available through the app, so viewers can switch between the two broadcasts during the game.
The Playoff Picture
The AL West race is simple for the Astros. A win clinches everything. The Rangers are out, and the Astros move forward. There is no room for a tiebreaker here — the win itself does the work.
The NL race is tighter. Arizona needs its own win and the Phillies to lose. That means the Diamondbacks are not controlling their own destiny entirely. They have to win, and they have to hope the Rays do enough to knock out Philadelphia.
Both games start at the same time, so viewers who want to watch both will need to pick which feed to watch first. Peacock handles the switching, so a viewer can start with the Astros and move to the Diamondbacks mid-game if they choose.

The Bottom Line
Today’s games are about control. The Astros control their own fate in the AL West, and the Diamondbacks control their own fate in the NL, provided the Phillies lose. Both games start at 3pm ET, and both are available on Peacock.
The broadcasts are straightforward. NBCSN carries the Astros game, and Peacock carries both. For most fans, the decision comes down to device support — what a viewer owns, and what works with it.
For anyone still deciding, the key question is which game matters more. The Astros need a win to clinch, and the Diamondbacks need a win plus a Phillies loss. Both games start at the same time, so choosing between them is a matter of preference.
The postseason schedule follows quickly after today’s games. The Wild Card Round runs from September 29 to October 1, and those games are exclusive to NBC, Peacock and NBCSN. That means the postseason is locked in for viewers who want to follow it from the first round.
