Colon is scheduled to pitch Tuesday when the Dominican Republic plays Venezuela.
Colon said he is free of shoulder soreness and the back pain he believes ultimately caused it.
"The way I see it, we're going to be competing ... and I'm going to go full bore," he said.
Scioscia said he is confident Colon would not be at any more risk for injury in the tournament than he would be in Angel camp, but pitching coach Bud Black said Colon, like other pitchers, almost certainly will exceed his normal spring routine.
"My concerns are, especially early, that in a game that has nationalism on the line the intensity is going to be different than an exhibition spring training game," he said.
"On the other hand, I'm excited for these guys. If they had this thing when I was pitching and they wanted me, I'm going."
The Angels' four Venezuelan representatives to the World Baseball Classic -- Francisco Rodriguez, Kelvim Escobar, Juan Rivera and Edgardo Alfonzo -- joined many of their countrymen on a flight from Phoenix to Tampa, Fla., on Thursday afternoon.
Rivera said he expected Omar Vizquel, Freddy Garcia and Carlos Zambrano, among others, on the same flight. They'll be shuttled to Clearwater, where they will train until Tuesday's opener against the Dominican Republic.
Noting the withdrawals of Dominicans Manny Ramirez, Vladimir Guerrero and Pedro Martinez, Rivera smiled and said, "We've got a chance."
Rodriguez and Escobar threw their regular bullpen sessions before leaving.
In a charity game that will not count in the Cactus League standings, the Angels had 15 hits and beat the Brewers, 12-1. Orlando Cabrera homered in the first and Jeff Mathis homered in the fifth.
