The Twins optioned Gray to Triple-A St. Paul on Friday.
With top prospect Kaelen Culpepper promoted for his major-league debut, Gray will head back to the minors after slashing .225/.267/.324 with four homers, 29 RBI, 16 runs scored, two stolen bases and a 10:60 BB:K across 188 trips to the plate with the Twins this season. Culpepper should get a long runway at shortstop in Minnesota.
