Macha said the bullpen sessions were just the beginning for Hawkins rehab.
"He is a long way off," Macha said. "He is going to have to do Spring Training [style rehab] to build up his strength."
Along with Hawkins, the return date for injured outfielder Jody Gerut remains uncertain. Gerut has taken batting practice recently, but he is still wearing a boot on his foot during games, Macha said.
