Lee said he feels ready to begin a rehab assignment, which could happen Sunday with Class A Clearwater. That decision could come Wednesday, when the Phillies and Lee see how his elbow responded from Tuesday's effort.
"I've been feeling better every day," Lee said. "A couple rehab assignments then hopefully back up."
If Lee makes two rehab starts he should be in line to rejoin the Phillies' rotation after the All-Star break, although the Phillies did not rule out just one rehab start and a return shortly before the break.
