Get ready for a jam-packed Sunday of MLB action, where two marquee matchups will take center stage. Whether you're a die-hard fan or just looking for some weekend entertainment, here's everything you need to know to catch the games live.
First up, the MLB Sunday Leadoff brings you an intriguing interleague clash between the Miami Marlins and the Tampa Bay Rays. Live coverage kicks off at 12:00 PM ET on NBCSN and Peacock. This isn't just any regular-season game—it's a chance to see two young, hungry teams battle for Florida bragging rights.
The Marlins are riding high after a remarkable turnaround in 2025. Under first-year manager Clayton McCullough, Miami posted a 79-83 record—a massive 17-win improvement from the previous full season (excluding the pandemic-shortened 2020 campaign). With the second-youngest active roster in the league, the Marlins are proving that youth and grit can go a long way.
On the other side, the Tampa Bay Rays are looking to bounce back after missing the playoffs for two straight seasons. Led by Kevin Cash—the current favorite for AL Manager of the Year—the Rays have the best record in the American League and are hungry to rewrite their recent narrative. Expect a high-energy showdown between two clubs with plenty to prove.
Joining the broadcast booth for Sunday Leadoff are World Series champion pitchers Brian Anderson and Jeff Nelson, alongside play-by-play voice Matt Vasgersian and reporter John Fanta. It's a lineup that promises insightful analysis and lively commentary.
Later in the evening, the action continues with Sunday Night Baseball at 7:00 PM ET, featuring the San Diego Padres vs. Seattle Mariners on Peacock and NBCSN. This primetime showcase is the perfect cap to a day of baseball, with two exciting teams looking to make a statement.
And mark your calendars for Sunday, July 5, when all 15 MLB games will be presented nationally across Peacock and NBC as part of a special all-day "Star-Spangled Sunday" celebration. Plus, NBC Sports will stream one out-of-market game each day throughout the 2026 season, so you'll never miss a moment of the action.
So grab your favorite team gear, settle in, and enjoy a full day of baseball. Whether you're tuning in for the rivalry, the young stars, or the playoff implications, this Sunday has something for every fan.
