Update 1:53 ET: According to LaVelle E. Neal of the Minneapolis Star-Tribune, the Twins are also getting cash in the deal, but she doesn't mention how much.
Update 1:18 ET: According to Bob Nightengale of USA Today the Minnesota Twins have acquired A's shortstop Orlando Cabrera for prospect Tyler Ladendorf.
According to ESPN The Magazine's Buster Olney, the Twins and Athletics are making "steady progress" on a deal that would send A's shortstop Orlando Cabrera to Minnesota.
The twins have been seeking infield help for some time now, and following the trades of Freddy Sanchez and Jack Wilson, Cabrera likely becomes the next best available.
Cabrera signed a one-year $4 million contract this offseason, so he will be a free agent after the season, which means most likely this would be 2 month rental at worst for the Twins.
At 34, Cabrera isn't getting any younger, and likely wouldn't command a huge market as a free agent, which should give the Twins a chance to resign him in the offseason, should they choose to do so.
