Team USA's World Baseball Classic roster came together in Phoenix with a mix of bonding activities and veteran leadership. Captain Aaron Judge addressed his teammates before their first workout at Papago Sports Complex, emphasizing the importance of getting to know each other quickly. The team gathered for dinner at the Global Ambassador Hotel where 23-time Olympic gold medalist Michael Phelps delivered a message about the importance of winning.

Several players shared their excitement about representing their country. Cal Raleigh, who hit 60 home runs last season, said playing for Team USA has been on his mind since accepting the invitation. Kyle Schwarber, back for his third international appearance despite a busy offseason with free agency and a newborn, emphasized the team's goal of winning gold after losing to Japan in 2023. Griffin Jax, the first Air Force Academy graduate to play in MLB, was particularly eager to join the team given his military background.

Young players like Roman Anthony, who joined the roster after Corbin Carroll's injury, are soaking up knowledge from the veteran stars. Brad Keller, who was fighting for a roster spot a year ago, now finds himself pitching for his country. The team's chemistry-building efforts included staying up until 1:45 a.m. sharing stories after their team dinner, with players bonding quickly despite having only been together a few days.
