Manoah will start Game 1 of the AL Wild Card Series against the Mariners on Friday, Kaitlyn McGrath of The Athletic reports.
The Blue Jays opted against using Manoah as a starter on the final day of the regular season Wednesday, and the right-hander will instead take the mound for the Blue Jays' first postseason game of the year. Manoah was dominant over six starts in September, posting a 0.88 ERA and 0.85 WHIP in 41 innings.
