Lawrie informed trainer George Poulis that he was feeling better and began swinging the bat on Friday.
"Brett felt better today. That doesn't give us any point on the calender that he is ready to get into games, but he is feeling better," manager John Farrell said.
Lawrie was forced to the disabled list after feeling pain in his oblique area during an at-bat against Oakland on Aug. 3.
Although the season is entering its final month, the Blue Jays have no intention, as of yet, to shut down Lawrie. He will presumably need to get into a few rehab games before joining the Blue Jays, but things could get tricky if he isn't ready soon, as the Minor League season is coming to an end. Lawrie could play with one of Toronto's Minor League affiliates that make the playoffs, which is the course of action the Blue Jays plan to take with injured starting catcher J.P. Arencibia, whose target date for return is Sept. 10.
Lawrie is known for his high-energy play, which was highlighted when he fell into a camera bay at Yankee Stadium in July and was forced to leave the game.
"He has a high-pain threshold, he's an ultra competitor," Farrell said. "There is nothing that he wants more than to be involved in winning a baseball game. As he goes through this experience, I think he is learning more about himself and is learning more when he can control his energy and effort level to be more efficient."
The third baseman, who's in his second Major League season, is batting .282 with nine homers, 40 RBIs, 13 stolen bases and a .742 OPS.
