Mets sign ex-Yankee lefty Sean Henn April, 12, 2013 MINNEAPOLIS -- The Mets have signed left-handed reliever Sean Henn to a minor league contract, Baseball America reports. Henn, 31, last pitched in the majors in 2009 with Baltimore and Minnesota. He began his career with the Yankees. Henn made 15 relief appearances with Triple-A Tacoma, a Seattle Mariners affiliate, last season. He was 3-0 with a 3.64 ERA in 29 2/3 innings through May. He reportedly then continued in South Korea. I like how he "reportedly" continued. Like independent evidence isn't available. Not a true Yankee, I hope.
