The Tigers selected Teheran's (back) contract Wednesday and added him to the 40-man and active rosters.
Tigers manager A.J. Hinch informed Teheran on Wednesday that he secured a spot in the Opening Day rotation after the non-roster invitee following four impressive appearances in Grapefruit League play. Over 11 innings, Teheran posted a 2.45 ERA and 0.64 WHIP while racking up 15 strikeouts. Detroit opened up a spot for Teheran on the roster and in the rotation by placing Spencer Turnbull on the COVID-19 injured list in a corresponding move. Turnbull isn't expected to be in store for a lengthy absence, so Teheran may need to pitch well in his first start or two with Detroit to strengthen his case for holding down a rotation spot when the Tigers' pitching staff is back to full strength.
