The 40-year-old Embree had an April 15 opt-out date in his contract with the Sox, but pushed that back to this Friday.
"There's not going to be any extending of the deadline anymore,” Embree told the Providence Journal from Pawtucket on Monday. "I've been a good soldier, I did whatever's asked, and I did what it took to get ready."
Promoting Embree might be in the offing for the Red Sox, whose bullpen has struggled of late. Embree, on the other hand, has been excelling with the PawSox. In his last five outings, Embree has pitched five scoreless innings and has not allowed a hit or walk while whiffing three.
"If something hasn't happened by [April 30], I think they know that I'm not going to consider staying,” Embree told the Journal. "So it's pretty much cut-and-dried. If I don't hear anything, I get on a plane and head home until I have a new job."
