San Jose, Costa Rica: Goalkeeper Keylor Navas and forwards Bryan Ruiz, Joel Campbell and Alvaro Saborio head the list of players named Monday to Costa Rica's preliminary 30-man squad for next month's World Cup in Brazil.
Coach Jorge Luis Pinto resisted naming any major surprises in the lineup and is using the same core of players who helped Costa Rica to qualify as the top team from the CONCACAF region.
Pinto said he was happy to stick with his proven players and valued continuity in the team.
"If we have to make changes, we will when the time comes," Pinto said.
He said he will name his final 23-man squad on May 31, before the team travels to the United States for friendlies against Japan and Ireland.
Pinto also confirmed that defender Bryan Oviedo of Everton will miss the cup with a broken left leg. Oviedo was injured in January and was not able to recover sufficiently to make the team.
Costa Rica will be a heavy underdog to advance from a group containing England, Italy and Uruguay.
The Central Americans will be appearing in their fourth World Cup, but merely picking up a point or two will be difficult against three teams near the top of the FIFA rankings with seven World Cup titles between them.
Knocking one of the European giants out of the World Cup and matching its achievement of reaching the round of 16, which happened in 1990, would be a major accomplishment.
