SEATTLE -- The Blue Jays have maintained that pitcher Shaun Marcum should be able to return from the disabled list shortly after the All-Star break. On Tuesday, some light was shed on just when exactly that time might arrive.

Should Marcum experience no setbacks in his recovery from a strained right elbow, Toronto pitching coach Brad Arnsberg said the starter could be activated by July 21 at the earliest. Even then, Arnsberg added that Marcum likely would be limited to around 60-70 pitches in his first outing.

The 26-year-old Marcum began a throwing program on Saturday at Toronto's complex in Dunedin, Fla., where he's playing catch on flat ground for the time being. Arnsberg noted that it will probably be at least another week before Marcum can pitch off a mound again.

Marcum has been sidelined since June 19 with strained ligaments around his elbow and forearm in his throwing arm. On June 23, the pitcher was examined by renowned arm specialist Dr. James Andrews, who determined that Marcum's injury didn't require surgery.

That was great news for the Blue Jays, who have benefited from a strong campaign from Marcum. In 15 starts this season, which is Marcum's second tour in Toronto's rotation, he's posted a 5-4 record with a 2.65 ERA, a .198 opponents' batting average and 86 strikeouts over 98 2/3 innings.
