Why can't the Mets hit Livan Hernandez? From Brian Costa today, via Rubin: "Since the Mets released him in August 2009, Hernandez has become a Mets-killer. In six starts against them, he has posted a 1.96 ERA, allowing just 1.09 walks and hits per inning. Against the rest of the league over that span, he has a 4.27 ERA and 1.40 WHIP."
