Folarin Balogun scored twice in the Americans' historic three-goal first half, and the US opened its first home World Cup in 32 years with its biggest win in the tournament, a dynamic 4-1 victory over Paraguay on Friday night. Christian Pulisic had an assist in a stellar first-half playmaking performance for the Americans, who enthralled their Southern California fans with an aggressive attack while streaking to a 3-0 halftime lead - the team's largest in any World Cup game. Gio Reyna ripped another goal in the dying moments of second-half injury time, giving the Americans four goals in a World Cup match for the first time.
