The New York Mets celebrated Johan Santana's birthday Wednesday morning with a quick team-wide gathering in a conference room and a cake with "34" on top. The southpaw already had realized this spring training that age is catching up with him as a pitcher. Santana has not been atop a mound in seven days, since he tried to ramp things up for a second time in spring training and his shoulder again told him he was not quite ready.
