Triple-A St. Paul placed Laweryson on its 7-day injured list Sunday due to an unspecified injury.
Before hitting the shelf, Laweryson had tossed 3.1 scoreless innings over three appearances for St. Paul after the Twins demoted him July 6. The right-hander has covered 16.2 innings over 15 outings at the big-league level this season, logging a 4.86 ERA and 1.38 WHIP while gathering one win, one save and two holds.
