The Twins recalled Helman from Triple-A St. Paul on Saturday.
Helman went 3-for-8 with two runs scored during his first stint in the majors earlier this month, and he'll now rejoin the active roster to conclude the season with Jose Miranda (back) headed for the IL. The 28-year-old utility man has played every position other than catcher throughout his professional career, though it's unlikely he cracks the lineup in the final two games of the year.
