Lawrence was designated for assignment by the Blue Jays on Monday, Arden Zwelling of Sportsnet.ca reports.
Lawrence struggled to a 8.78 ERA through 13.1 innings with the Blue Jays earlier in the season before being optioned back to Triple-A. While he did much better with Buffalo, posting a 0.90 ERA through 10 innings, the Blue Jays decided to oust him from the 40-man roster to clear room for backup catcher Mike Ohlman. He'll likely head back to Buffalo if he clears waivers.
