The Blue Jays have designated right-hander Donn Roach for assignment, the club announced. In a corresponding move, the Jays selected the contract of infielder Jonathan Diaz, who will join the team for the first game of their double-header today in Baltimore.
Roach has now been designated three times by as many different teams this season, as he was previously DFA’ed by the Cubs in July and the Reds in August. Toronto claimed the righty off waivers from Cincinnati following that last designation. The 25-year-old Roach has appeared in just one MLB game this season (with the Cubs) but has posted a 3.34 ERA, 2.04 K/BB rate and a 3.3 K/9 over 143 innings at the Triple-A level. Roach was originally a third-round pick of the Angels in the 2010 draft and he has a 5.35 ERA over 33 2/3 career innings in the majors.
This is Diaz’s second stint on the Jays roster this season, as he appeared in four games in April and May. The 30-year-old infielder hit .223/.328/.284 over 430 PA for Triple-A Buffalo this season, his 10th pro campaign. Diaz has played 32 career games at the Major League level, with Boston and Toronto in 2013-15.
