Burdi has 2 more weeks of rehab, but TJ surgery guys are eligible to apply for up to 30 days extra rehab too. They could also reset his rehab with a week's break, like we did with Ervin Santana earlier this season. And they just have to extend it to Sep. 1st, when they can activate him with expanded rosters even if they don't plan to pitch him. (Assuming they can bump someone else from the 40-man at that time.) If not returned, Burdi would still need MLB time next year to satisfy his Rule 5 requirements. About 2 months, if he gets activated Sep. 1 this year. Personally, I am not convinced Burdi is worth all that much trouble, though. Seems like minor league relievers with his profile are a dime a dozen these days.
