Ken Rosenthal of FOX Sports reports that the Mariners placed Jason Vargas and Kevin Millwood on revocable waivers on Monday. Both are likely to be claimed, though they may not make it out of the American League. Vargas is 13-8 with a 3.75 ERA and a 111/45 K/BB ratio in 180 innings this season and is under team control for another year. The 37-year-old Millwood has a 4.28 ERA and a 100/48 K/BB ratio in 145 innings this year and will be a free agent this offseason.
