Friday has been a busy day on the waiver wire for the Twins.

The Orioles claimed infielder Alexi Casilla, and the Twins claimed two players from the Rockies -- reliever Josh Roenicke and shortstop Tommy Field. Also, the Twins took starting pitcher Samuel Deduno off their 40-man roster and assigned him to Class AAA Rochester.

Deduno has the right to accept that assignment or become a free agent. Deduno went 6-5 with a 4.44 ERA in 15 starts this year, so the move was a little surprising.

Update: I spoke to Deduno's agent, Paul Kinzer, who said Deduno is weighing his options right now but probably will re-sign with the Twins on a minor-league deal.

The Twins were expected to non-tender Casilla this offseason rather than give him another raise from his $1.38 million salary through arbitration. He batted .250 with a .305 on-base percentage in seven years with the Twins, though he will always be remembered for delivering the game-winning hit in their Game 163 victory over the Tigers in 2009.

Casilla, 28, became expendable when the Twins traded Francisco Liriano to the White Sox in a deal that brought utility infielder Eduardo Escobar. Jamey Carroll also can play multiple infield positions, and the Twins have two young shortstops they like in Pedro Florimon and Brian Dozier.

Now, Field has been added to the mix. The 25-year-old played two games for the Rockies this year and batted .246 with a .715 OPS last year at Class AAA Colorado Springs.

Roenicke, 30, the son of former Orioles outfielder Gary Roenicke and nephew of Brewers manager Ron Roenicke, posted a 3.25 ERA in 63 appearances for the Rockies last year. He had 54 strikeouts and 43 walks in 88 2/3 innings and his fastball averaged 92.3 mph, according to Fangraphs.com.

Update: It doesn't sound like the Twins will re-sign Scott Baker before the free agent market opens at 11 p.m. At that point, other teams will be able to bid. At this point, Baker might need to see what offers are out there before deciding if it's best to remain in Minnesota or move on.
