J.A. Happ is aiming for a return to the Blue Jays by the All-Star break.
Happ was hit in the head by a line drive on May 7 and hasn't pitched since.
The liner off the bat of Tampa Bay's Desmond Jennings left Happ with a fractured skull, contusions and a sprained right knee.
"I was in a brace for several weeks and am now moving, jogging and regaining athleticism," Happ said. "I began running again three or four days ago, and I'm not quite there yet as far as cutting or turning."
