Beltran has not yet begun full baseball activities, according to the general manager. Once he does, he will still need four to six weeks of rehabilitation before he can return to the active roster.
Minaya said that team doctors will have the final say regarding Beltran.
"It's in their hands as far as deciding when," he said.
Though Beltran has been jogging and taking batting practice daily at the team's Spring Training complex in Port St. Lucie, Fla., he has not yet progressed to sprinting.
When the Mets first announced Beltran's right knee surgery in January, they estimated that he would be able to return to full baseball activities by the first week in April. But more than seven weeks have passed since that time, and Beltran remains limited.
Now, the soonest Beltran could return to the Mets is early July. More likely, he will remain in Florida until after the All-Star break and quite possibly even longer than that.
One team official also brushed aside speculation that Angel Pagan's hot play will force the Mets to move Beltran to right field when he returns. The Mets, according to the official, have no such plans.
