After a historic debut in 2023 that saw them secure their first-ever win against Colombia, Great Britain enters the 2026 World Baseball Classic with a new look and higher expectations. This year marks the first time the team has automatically qualified for the tournament, and they are bringing a roster that blends the elite speed of their previous squad with a significant influx of major-league talent.

The most notable addition is All-Star infielder Jazz Chisholm Jr., who joins the roster as a co-captain alongside breakout star Harry Ford. Now with the Washington Nationals, Ford remains the heart of the team after a dominant 2023 performance. The squad also features a massive boost to the rotation with the addition of brothers Tristan and Brendan Beck, giving Great Britain a legitimate frontline pitching presence to match their explosive outfield.

Here's the complete roster for Great Britain in their second Word Baseball Classic.

Great Britain players to watch in World Baseball Classic

Jazz Chisholm Jr. is the biggest star to ever wear a Great Britain uniform. The Bahamian-born standout brings elite power and speed to the top of the order, providing the kind of game-changing athleticism that could propel Team GB into the knockout stages. He is joined by Harry Ford, who became a national hero in 2023 and has since made his MLB debut, cementing his status as one of the premier young catchers in the world.

In the outfield, Trayce Thompson, the brother of NBA Star Klay, returns to provide veteran power and leadership. He is flanked by Matt Koperniak, a St. Louis Cardinals prospect who has been rising through the ranks, and speedster Anfernee Seymour. The team’s philosophy remains built on pressure; with the base-stealing abilities of Lucius Fox and Darnell Sweeney, Great Britain looks to be one of the most aggressive teams on the basepaths in Houston.

The pitching staff is headlined by Tristan Beck of the San Francisco Giants and his brother Brendan Beck, a top pitching prospect in the Yankees' system. They are supported by returning veterans like Vance Worley, who brings over 600 innings of MLB experience, and hard-throwing relievers like Michael Petersen and Tahnaj Thomas.

Great Britain World Baseball Classic history

Great Britain successfully moved from newcomer to competitor in 2023. After sweeping through the 2022 Qualifiers, they pulled off a stunning 7-5 upset over Colombia in pool play. Because the United States subsequently defeated Colombia, Great Britain finished fourth in their pool, which granted them automatic qualification for the 2026 tournament — sparing them from the qualifying rounds for the first time.
