The 29-year-old Bolsinger made five starts and six relief appearances for the Jays this season, posting a 6.31 ERA, 8.5 K/9 and 5.9 BB/9 while allowing nine home runs in 41 1/3 innings. This is the third time he’s been designated for assignment this year. The soft-tosser had allowed runs in all of his previous five appearances, including four yesterday against the Astros. He’s also pitched for the Diamondbacks and Dodgers in a big-league career that spans parts of four seasons.
The 27-year-old Cole has missed most of the season to injury, but hasn’t yet allowed a run in 12 2/3 innings spanning three minor-league levels. The 2011 29th-round pick has moved through the Jays’ minor-league system slowly despite generally good performances, including a 2014 season in which he whiffed 181 batters in 144 1/3 innings at Class A+ and Double-A. He has never pitched in the big leagues.
