The Twins are expected to call up Castillo from Triple-A St. Paul on Sunday, Betsy Helfand of the St. Paul Pioneer Press reports.
Minnesota is currently dealing with several injuries in the infield and Castillo is expected to take the 26-man roster spot of the IL-bound Jose Miranda (back). Castillo logged just one big-league at-bat last season and is slashing .269/.375/.399 with five homers and seven stolen bases across 283 games with St. Paul. The 26-year-old should see work at third base and could mix in at second base and shortstop if needed. The Twins will need to free up a spot on the 40-man roster for Castillo.
