Major League Baseball officially announced the rosters for the 20 teams participating in the 2026 World Baseball Classic on Thursday night, and 11 players on the Red Sox big league club are set to take part.

This year’s participating Red Sox include Garrett Whitlock (USA), Ranger Suarez, Willson Contreras and Wilyer Abreu (Venezuela), Brayan Bello (Dominican Republic), Jarren Duran (Mexico), Ceddanne Rafaela (Netherlands), Masataka Yoshida (Japan), Greg Weissert (Italy), Jovani Moran (Puerto Rico) and Nate Eaton (Great Britain).

Minor league right-hander Jack Anderson is also on Great Britain’s roster, and assistant hitting coach Dillon Lawson and High-A Greenville manager Liam Carroll will serve on Great Britain’s coaching staff. Tayron Guerrero, a 35-year-old right-hander and a Red Sox non-roster invitee, is on Colombia’s roster, and minor league lefty Eduardo Rivera will play for Puerto Rico.

Though most of the participating Red Sox had either announced their intention to play or were confirmed by their respective country’s governing body ahead of time, several had been in limbo. Contreras, for instance, told reporters during his introductory press conference last month that he was having trouble getting cleared by insurance, and Moran reportedly faced significant difficulties getting approved as well.

Several Red Sox players who hoped to play were not able to gain approval.

Left-hander Aroldis Chapman was originally expected to suit up for Great Britain, but according to multiple reports was denied due to eligibility issues. The Cuban-born flamethrower had sought to play for the British squad because his family lineage traces back to Jamaica at a time when the island nation was a British colony, but his documentation was rejected.

Marcelo Mayer (Mexico) and Carlos Narvaez (Venezuela) were also denied by insurance due to recent injuries.

There had also been rumors earlier in the winter that Roman Anthony might suit up for Italy, but the second-year Red Sox standout shot those rumors down at Fenway Fest, saying he wants to focus on preparing for his first full season in the majors.
