Stalemate for USA and Chile
Estaban Paredes, the only player on the pitch to play at the 2010 FIFA World Cup South Africa™, had put the visitors ahead in the 53rd minute when he fired home from short range from a cross by Felipe Seymour.
Second-half sub Bunbury, whose father Alex was a Canadian international, levelled the match from the spot in front of the 18,580 spectators after 18-year-old Juan Agudelo had been brought down in the area.
For Chile the match at the Home Depot Center was part of preparations for the Copa America in Argentina in July, while the United States used it to try out some new players ahead of this year's CONCACAF Gold Cup.
Seven US players made their international debuts, including goalkeeper Sean Franklin, left back Zach Loyd, midfielder Jeff Larentowicz and forward Chris Wondolowski.
