One of the CONCACAF Gold Cup favorites, Costa Rica did all it needed to do and more in the first 17 minutes to beat game but outclassed Guatemala, 2-0, Saturday at the Rose Bowl.
Midfielder Roger Gomez scored in the 14th minute, followed by a goal three minutes later by forward Leroy Flores.
Costa Rica also scored a second-half goal, but it was nullified because of an offsides penalty.
Starting times for Monday's games at the Rose Bowl have been changed. The Costa Rica-Trinidad and Tobago game will begin at 6:15 p.m., while the U.S.-Guatemala game will begin at 8:15 p.m. CONCACAF's secretary general, Chuck Blazer, said that a local ordinance requiring promoters to pay an additional fee for each minute an event continues after 10 p.m. necessitated the changes.
