Gregg signed a minor league contract with the Mariners on Wednesday, Shannon Drayer of 710 AM ESPN Seattle reports. The former closer was clobbered for 12 runs on 13 hits -- including three homers -- in 11 appearances with Cincinnati to begin the year, struggles which were compounded by manager Bryan Price's insistence on using Gregg in high-leverage situations. It led to his designation for assignment last week, but the 36-year-old Gregg will have an opportunity to return to the majors with Seattle if he's able to get it together at Tacoma.
