MINNEAPOLIS -- As the non-waiver Trade Deadline passed at 3 p.m. CT on Wednesday, it appeared the Twins had stood pat.

But news trickled out shortly after the Deadline that Minnesota had made a move, but it didn't involve any of the names linked to trade rumors in recent weeks such as Justin Morneau, Glen Perkins or Mike Pelfrey.

Instead, the Twins sent Triple-A Rochester catcher Drew Butera to the Dodgers for a player to be named.

Butera, 29, was hitting .229/.258/.325 with two homers and 10 RBIs in 26 games at Triple-A. He also appeared in two games with Minnesota over the weekend in Joe Mauer's absence, going 0-for-3.

Butera, regarded as a top defensive catcher, spent parts of four seasons with the Twins, but struggled offensively. In 186 games with Minnesota, he hit just .182 with five homers and 41 RBIs.

So while it was a surprise the Twins dealt Butera, it was also surprising that Minnesota didn't trade any players from its big league roster.

Morneau appeared the most likely to be dealt, but he was in the Twins' lineup on Wednesday against the Royals, batting fourth and starting at first base.

But the Twins could still decide to move pieces in August. Morneau and Pelfrey are still candidates to be traded after the non-waiver Deadline as well as Kevin Correia, Jared Burton, Jamey Carroll and Ryan Doumit.

Now that the non-waiver Trade Deadline has passed, deals involving players on the 40-man roster can't be made unless the players already have cleared waivers. In other words, the player must be offered to the other teams in reverse order of the standings, and if he is claimed by one of the teams, he cannot be traded. The club that placed the player on waivers can either withdraw the request and keep the player, or let the player go to the claiming team, which would then have the rights to the player.
