TORONTO -- Injured Blue Jays reliever Brett Cecil has resumed throwing and is feeling "really good," but there is still no timetable to begin a rehab assignment.

Cecil has been out since May 15 because of a torn lat muscle. He is expected to be out until at least the middle of June, but once he begins a rehab assignment, it shouldn't take long before Cecil is back in the big leagues.

The veteran lefty is working out at the club's Minor League complex in Dunedin, Fla. The club has decided to take a cautious approach to avoid any potential setbacks, but it sounds like his workload could be increasing in the near future.

"Really good," Blue Jays general manager Ross Atkins said when asked how Cecil has been doing. "He's feeling no pain, he's throwing now, so he could start to be in bullpens relatively soon, but don't want to get ahead of ourselves either. Want to make sure that's completely past him."

Cecil got off to a disappointing start this season and was 0-5 with a 5.23 ERA at the time of his injury. He has been a slow starter in the past, but Cecil remains a key piece of Toronto's bullpen moving forward. Aaron Loup and Chad Girodo will continue to split the primary left-handed reliever duties until he returns.
