Livan Hernandez, designated for assignment by the Minnesota Twins on Friday, should learn Tuesday whether he has cleared waivers and will become a free agent -- and if he does, he is expected to have an array of choices among contenders, including the New York Mets and Colorado Rockies. Hernandez, 33, was 10-8 with a 5.48 ERA with the Twins, averaging almost exactly six innings in his 23 starts; he had allowed 199 hits in 139.2 innings, with 29 walks and 54 strikeouts.
