Starting Saturday, all teams can expand their active rosters to 40 players, but the Twins are expected to call up only a few players.
Ryan said he expects to meet with Twins manager Ron Gardenhire sometime during Minnesota's four-game homestand against the Mariners to talk about who will be their September callups.
"We're going to have a session in the next couple of days," Ryan said. "I have a fair idea of who I'm going to talk to him about that people are recommending and people I saw that I would recommend. There has to be a fit."
Candidates to be called up from Triple-A include first baseman Chris Parmelee, shortstop Brian Dozier and starting pitchers Esmerling Vasquez and P.J. Walters. Ryan also wouldn't rule out calling up a player from Double-A, so outfielder Oswaldo Arcia is a strong possibility.
"There will be some new faces," Ryan said. "The types of guys we're talking about are guys who have earned the promotion from what they've done at Triple-A or Double-A. We want an opportunity to get plenty of a look here, because we don't want to bring up a guy just to have the experience. I don't buy into that."
