Matt Cain met with Evan Longoria in Santa Monica on Tuesday to play a "Call of Duty" video game.

"We'll have a little grudge match together," Cain said in a phone interview, "and then take it into the season and have another grudge match."

Giants-Rays World Series?

In reality, the opponent doesn't really matter for Cain.

"We have every opportunity to be as good as we were last year," said Cain, the starting pitcher in each of the Giants' three series-clinching wins in the postseason. "We have pretty much the same team. The way everyone came together, that was a big part of our success. We had a great clubhouse, and to be able to bring that back, it's an advantage for us."
