Two the USA’s Group D World Cup opponents were in action yesterday. Portugal tied Brazil, 1-1, in Lisbon in a performance that eases concerns raised after its 4-1 loss to Finland in March. Poland experienced no such rebound. It lost its second straight game at home, 2-1, to non-qualifier Romania on the heels of its 2-0 loss to Japan in March. Coach Jerzy Engel changed his formation from a 4-4-2 to a 3-5-2, but his team was again victim of major defensive lapses. Poland’s top player, striker Emmanuel Olisadebe, missed the Romania game because injury.
