Gold cup warm-up for two teams that will hope not see each other again until the final of the CONCACAF tournament on July 26.
This is merely a friendly, but there is a little pressure building on Mexico to validate the decision to send a B-team to Copa America by putting in a suitably dominant display in Gold Cup. Losing to Costa Rica - winless to date in 2015 - would not be an encouraging sign, though this is not a competitive match so expectations ought to be tempered a little.
But Los Ticos are missing several key players to injury - Keylor Navas, Oscar Duarte, Bryan Oviedo, Yeltsin Tejeda - whereas El Tri is expected to showcase a new-look, all-star attack: head coach Miguel Herrera has said he will start Chicharito Hernandez, Giovani dos Santos and Carlos Vela together.
That is as potent a front-line as there is CONCACAF at the moment - on paper, at least. Roy Miller and Los Ticos should get a thorough pre-tournament work-out.
