Frasor hasn't pitched since July 16 when he was shut down with tightness in his right forearm. He has been on a long-toss program out to 120 feet and after three more sessions will likely be cleared to start working off a mound.
"There's not an exact return date yet but [he] feels good about himself, his arm has had no issues as far as the work he has been undergoing and is in good shape," Blue Jays manager John Farrell said of the veteran reliever who has a 4.00 ERA in 42 games this year.
The news isn't as positive for designated hitter for Adam Lind, who was shut down in late July with soreness in his mid-back. The injury was originally expected to keep Lind out for just 15 days but the pain has not subsided and as a result his baseball activities continue to be limited.
"Lind has been still swinging off a tee and taking some soft toss," Farrell said. "So, that's a little bit slower than first anticipated."
David Cooper has done a relatively solid job filling in during Lind's absence. Cooper has seven extra-base hits in 15 games since being recalled from Triple-A Las Vegas and has found a way to come through in timely situations. He entered play on Wednesday night hitting .415 (17-for-41) with three doubles and three homers from the seventh inning on.
