The Blue Jays designated Dolis for assignment Wednesday, Kaitlyn McGrath of The Athletic reports.
Dolis held some fantasy relevance earlier in 2021 when he notched three saves just over a month into the season, but he's slowly tumbled down the pecking order in the Toronto bullpen. The 33-year-old right-hander hadn't recorded a hold or a save since June 1, and after giving up at least one run in each of his last three appearances in a low-leverage role, Toronto elected to move him off the 40-man roster. The Blue Jays activated reliever Tim Mayza (elbow) to fill Dolis' spot in the bullpen.
