Mexico secured a 1-0 victory over Jamaica in their Copa América Group B opener, with a stunning goal from Gerardo Arteaga in the 69th minute. However, the win was overshadowed by a potentially tournament-ending hamstring injury to their captain, Edson Álvarez, who was forced to leave the pitch in tears in the first half. Jamaica had a goal disallowed for offside in the 50th minute, which would have been their first-ever Copa América goal. Despite the setback, Mexico's dominance was evident as they recorded 17 shots, with Jamaica's goalkeeper Jahmali Waite making several crucial saves. Coach Jaime Lozano and defender Cesar Montes highlighted the emotional and tactical importance of Álvarez, whose condition remains uncertain pending further medical evaluation.
