Devil Rays' Seo headed to minors; RHP Hammel called up

ST. PETERSBURG, Fla. -- The Tampa Bay Devil Rays recalled right-hander Jason Hammel from Triple-A Durham and said Monday that right-hander Jae Seo accepted an assignment to the minor league affiliate.

Hammel, 0-6 with a 7.77 ERA in nine starts for the Devil Rays last season, fills one of two openings created when Tampa Bay optioned relievers Chad Orvella and Tim Corcoran to Durham after Sunday's game against Florida Marlins. The other roster spot will be filled on Tuesday.

Seo, 3-4 with an 8.13 ERA this season, was designated for assignment on June 2. Hammel was 4-5 with a 3.42 ERA in 13 starts at Durham.
