Highlights - Rampant Brazil beat USA (UK users only)
Holders Brazil virtually booked their place in the semi-finals of the Confederations Cup with a comprehensive victory over 10-man USA in Pretoria.
Brazil took the lead after five minutes when Felipe Melo rose highest to head home a Maicon right-wing free-kick.
Robinho side-footed in Brazil's second, finishing off a sweeping counter-attacking move following a USA corner.
USA's Sacha Kljestan was sent off for fouling Ramirez and Maicon chipped in a third goal for Brazil.
Monday's 4-3 win over Egypt was a wake-up call for a tired Brazil squad and they set about the task of securing the victory that would secure their qualification in alert, energetic fashion.
The constant sound of horn-blowing supporters aptly rang around the stadium as Brazil orchestrated a cavalry charge that the USA were powerless to resist, offering defensive naivety and ineptitude in possession in return.
Five minutes in, Brazil were ahead when a right-wing free-kick was swung across by Maicon - in for Daniel Alves at right-back - which was met powerfully by midfielder Felipe Melo, outmuscling Jonathan Spector to plant a header past Tim Howard in the American goal.
USA were their own worst enemy in conceding the second goal as Rangers' DeMarcus Beasley miscontrolled a corner, allowing a rapid Brazil counter-attack that passed speedily from Kaka to Ramirez and finally to Robinho unmarked in the box to side-foot home with ease.
The Manchester City striker's celebration included a brief interview with a microphone wielding journalist, underlining just how much the match was over as a contest.
Any faint, optimistic hopes USA had of getting back into the game were extinguished on the hour when Kljestan was shown a straight red for a lunging tackle on Ramirez.
Shortly after, Maicon made it 3-0 to Brazil, cutting in from the right to receive a short pass from Kaka before chipping expertly over Howard into the far corner of the net.
In the final 10 minutes, USA substitutes Benny Feilhaber and Casey Conor hit the crossbar - with a powerful shot and glancing header respectively - but any consolation goal would have flattered the Americans, who are now virtually eliminated from the competition.
Brazil will be sure of a semi-final place later on Thursday if Egypt fail to beat Italy in the other Group B match in Johannesburg.
