To make room for Nolin on the 40-man roster, the Blue Jays transferred left-hander J.A. Happ to the 60-day DL. Happ has not thrown off a mound since he was struck in the head by a comebacker two weeks ago. While his head injuries are mostly healed, he also suffered a sprained right knee that has delayed his return.
Toronto selected Nolin's contract from Double-A New Hampshire, where he was 2-0 with a 1.17 ERA in three starts. Friday will be the Major League debut for the 23-year-old lefty, the club's sixth-round pick in the 2010 First-Year Player Draft, who is ranked by MLB.com as Toronto's eighth-best prospect.
