Two of the few things that went right for the Mets early this season joined all the others on Tuesday when ancient starter David Cone 16 and revived right fielder Jeromy Burnitz 20 finished a depressing 6-2 loss to Houston on the disabled list. Cone should … uh, could be gone forever; Burnitz will miss up to 6 weeks with a hand broken by a wild Billy Wagner fastball. In their place, the Mets recalled outfielder Raul Gonzalez 21, utilityman Joe McEwing 11 and pitcher Pat Strange 38. Strange was sent back to Norfolk after Wednesday’s win so the Mets could re-able Pedro Astacio 34, who is scheduled to start today.
