The Twins selected Culpepper's contract from Triple-A St. Paul on Friday.
Culpepper will take over at shortstop for the Twins moving forward after slashing .271/.367/.478 with 14 homers, 46 RBI, 63 runs scored, 17 stolen bases and a 39:64 BB:K across 343 plate appearances with St. Paul this season. With power and speed upside, Culpepper should be added in all fantasy formats. He's batting seventh in his major-league debut Friday against Brewers lefty Shane Drohan.
