Comcast’s Peacock Streams MLB Sunday Tripleheader Led by Marlins vs. Nationals

Comcast Corporation is set to broadcast a comprehensive lineup of Major League Baseball games this Sunday, featuring a tripleheader across its NBCUniversal platforms. The programming begins with the MLB Sunday Leadoff contest between the Miami Marlins and the Washington Nationals at Nationals Park.

The early matchup, scheduled for a 12:00 PM ET first pitch, will air on NBCSN and stream exclusively on Peacock. The broadcast team will feature Tom McCarthy making his debut on the MLB Sunday Leadoff show. He will be joined by analysts Jeff Nelson, a four-time World Series champion, and former Washington infielder Kevin Frandsen, with Jordan Cornette serving as the field reporter.

Following the Nationals game, Comcast’s coverage continues with a matchup between the Houston Astros and the New York Mets at Citi Field at 3:00 PM ET. The day concludes with the primetime Sunday Night Baseball showcase, as the Cincinnati Reds visit the Chicago Cubs at Wrigley Field for a 7:00 PM ET start. Both the afternoon and primetime games will be available on NBC and Peacock.

These broadcasts are part of Comcast’s broader strategy to integrate live sports into its Peacock streaming service. The MLB Sunday Leadoff serves as a weekly daytime highlight, while Sunday Night Baseball anchors the network’s evening sports lineup. Looking ahead, the company plans to stream one out-of-market game nationally on Peacock every day during the 2026 season. Spanish-language coverage will be provided by Telemundo Deportes and Universo.

Currently, Comcast Corporation trades in the Communication Services sector. The stock was last observed at $26.41, reflecting a slight increase of 0.11% from the previous close. The company maintains a market capitalization of approximately $96.01 billion.
