Cliff Lee will throw his third bullpen session on Tuesday as he continues to progress toward a return from the disabled list.
Lee, on the DL since May 20 with an elbow strain, will have an "up-and-down" bullpen session Tuesday, during which he'll throw about 25 pitches, sit down, get back up and throw some more.
If all goes well, Lee could then pitch a simulated game at Citizens Bank Park on Saturday. From there, it is unclear whether he'd need a rehab start or two, but Phillies manager Ryne Sandberg said it would likely be recommended.
"I don't know if it's one or two [rehab starts], but I would think it would be something more than a simulated game," Sandberg said.
"He’s progressing fine, passing all of the tests. His first bullpen was quality with location and stuff, and rebounding from it the next day with the way he felt. All positive."
Barring any setbacks, this means that Lee could possibly be back before the All-Star break. A first rehab assignment would likely come in the first few days of July. The Phils' final game before the All-Star Game is July 13.
The Phillies have gone 15-18 since Lee hit the DL. David Buchanan has made six starts in his stead and gone 3-3 with a 4.95 ERA.
