Anthony DiComo of MLB.com reports that the Mets attended a throwing session for Joel Hanrahan (elbow) on Thursday. CBS Sports' Jon Heyman reported last week that the Yankees, Royals, Athletics, Red Sox, and Dodgers were among the other teams expected to be in attendance. Hanrahan is working his way back from Tommy John and flexor tendon surgeries and should be ready to contribute in the majors soon. The Mets might make sense for him, as he could get some save chances with Bobby Parnell (Tommy John surgery) out for the year and Jose Valverde appearing quite vulnerable.
