The Twins selected Jenkins' contract from Triple-A St. Paul on Friday.
News broke Thursday that Jenkins was on his way to the big leagues, and his promotion is now official. The top prospect missed time with a shoulder injury this season, but when healthy he slashed .308/.407/.532 with 12 home runs, 17 stolen bases and a 42:48 BB:K over 69 games with St. Paul. Jenkins has primarily been a center fielder in the minors, but he's capable of handling all three outfield positions. He's starting in center field and batting ninth Friday versus the White Sox in his major-league debut.
