SEMIFINALS
CHILE vs. COLOMBIA
Where: Chicago. Time: 5 p.m. PDT Wednesday. TV: FS1, UDN.
The buzz: Chile, the reigning Copa America champion, embarrassed Mexico, 7-0, in its quarterfinal, handing El Tri the worst competitive loss in its history. Eduardo Vargas scored four times in that game and leads the tournament with six goals. But Chile will be weakened here by the loss of midfielder Arturo Vidal, who will sit out with two yellow cards. And though midfielder Marcelo Diaz and forward Alexis Sanchez are likely to play, they could be less than 100%, with media reports saying neither trained fully this week because of injury concerns.
