The United States-Japan match was not the only one played on Thursday, though it may have seemed like it. In fact, the US wasn't the only CONCACAF nation to kick off their quest for gold either.
But Honduras didn't fare quite as well as the Americans.
Italy routed Honduras 3-0. Giussepe Rossi scored one of the Italians' goals. Funny how an American scored a goal in the first day of the Olympics and it didn't come in the United States' game - Stuart Holden, the United States' goal scorer, was born in Scotland.
In a game of note for the US, the Netherlands and Nigeria tied 0-0. That puts the US atop the group with three points. If the US beats the Netherlands on Sunday and Nigeria-Japan ends in a draw, the US will clinch a spot in the knockout rounds.
Brazil beat Belgium 1-0 with a late winner from Hernanes. The goal was apparently a fantastic one though we didn't have a chance to see it.
Australia and Serbia tied 1-1. Ruben Zadkovich scored for the Aussies while Slobodan Rajkovic equalized .
Other scores (sorry, no links yet for these games): Argentina beat Ivory Coast 2-1. Lionel Messi scored for Argentina but Sekou Cisse equalized. Lautaro Acosta won the match with an 86th-minute goal.
China-New Zealand and Cameroon-South Korea each finished in a 1-1 draw.
