Busenitz had his contract purchased from Triple-A Rochester ahead of Game 2 of Saturday's doubleheader against the Indians, Phil Miller of the Minneapolis Star Tribune reports.
As expected, Busenitz will join the Twins as an extra bullpen arm Saturday. He'll take the spot of Adam Wilk, who was designated for assignment following Game 1. Although Busenitz isn't considered a top prospect, he could stick around in the big-league bullpen if he is able to replicate the impressive numbers he put up with Rochester (2.15 ERA and 32:9 K:BB in 29.1 innings).
