April 13: The Blue Jays were not able to trade Jeffress, and have placed him on waivers, Shi Davidi of SportsNet.ca tweets.

April 4: The Blue Jays announced that they have designated reliever Jeremy Jeffress for assignment, tweets Ben Nicholson-Smith of Sportsnet.ca. In a corresponding move, the team recalled righty Marcus Walden to take his roster spot, the club announced.

Jeffress, 26, gave up three hits and a run tonight in what could have been his last appearance for Toronto. He has seen MLB time in five seasons, but has never logged more than 15 1/3 innings in any one season. Jeffress has yet to harness his big arm, as his career 6.7 BB/9 tally in the bigs would indicate. He did put up outstanding results last year, as he put up a 0.87 ERA in 10 1/3 big league frames (10.5 K/9 against 4.4 BB/9) and a 1.39 mark in his 32 1/3 minor league innings (8.4 K/9 against 3.6 BB/9).
