Alex Rios of Puerto Rico on WBC title game

You'd think he'd be preparing for tonight's World Baseball Classic championship game, but Puerto Rico and Chicago White Sox outfielder Alex Rios was working at a Subway restaurant in San Francisco this afternoon, surprising customers.

Rios, who hit the two-run homer against Japan on Sunday to propel his team into the championship game against the Dominican Republic, said his squad is ready.

"We know what our goal is. We're optimistic with the talent we have," said Rios, who batted .304 for the White Sox last season. "If we do what we need to do, anything can happen. We are focused."

That might be easier said than done, as Puerto Rican is running into a buzz saw with the Dominican Republic (7-0), which hasn't lost a game in this tournament. In fact, D.R. has beaten Puerto Rico twice already.

Rios said no matter who wins, playing in the WBC is special for both teams, more than people might think.

"It means a lot to us, seeing the reaction of the fans and the enjoyment we bring," said the 32-year-old Rios. "It's been a great experience for all of us. We have so much pride and excitement, and it's been a great ride."
