Orioles manager Buck Showalter touched on a number of subjects during his sit-down with the national media on Monday, including the status of second baseman Brian Roberts and the likely composition of the infield next season.

Showalter said the reports he is getting in his periodic conversations with Roberts are encouraging, but he can’t predict whether his veteran second baseman will be ready to play full-time next spring.

“We don’t have any reason to think one way or the other,’’ Showalter said. “It’s an inexact science. I’m not going to sit here and say I’m an expert on concussions. So far, so good.”

If Roberts cannot play regularly, Showalter said that he was pleased with the way Robert Andino stepped into the role last year.

“I think Robert established that he can make a contribution no matter where you need him,’’ Buck said. “I feel good about what he did last year, but I’d still like to have both of them.”

Depending on what happens over the next few months, Showalter also said that he still is not certain that Mark Reynolds will be the full-time first baseman. He indicated that both Chris Davis and Reynolds are still possibilities at third, and newcomer Matt Antonelli could also be in the mix.
