Alou To Undergo Hernia Surgery. Those Mets are dropping like flies. The International Man of Injury himself - Moises Alou - joins the list as he gets to work a little earlier this year. After leaving Spring training for New York today due to soreness in his groin, tests revealed a hernia which required surgery - a procedure which will take place tomorrow. Alou is expected to stop all baseball activities for the next four to six weeks. He will most likely miss most - if not all - of April.
