The Twins designated Laweryson (undisclosed) for assignment Saturday, Dan Hayes of The Athletic reports.
Laweryson will give up his 40-man roster spot to A.J. Minter, who officially joined the Twins on Saturday after being traded from the Mets on Thursday. Laweryson owns a 4.86 ERA and 1.38 WHIP through 16.2 innings in the majors this year and hasn't pitched at Triple-A St. Paul since July 17 due to an unknown injury.
