(NEWSER) – A former California Little League coach is backpedaling after suing one of his players for more than half a million dollars. Alan Beck's suit claims that the 14-year-old "carelessly threw his helmet" while rounding the bases after a walk-off hit in March, KCRA reports. Beck says the helmet hit him, and caused him to tear his Achilles tendon, though he didn't have surgery until December. Now, he's seeking more than $100,000 for medical expenses, and $500,000 for pain and suffering. "At first, I thought it was a joke," says the boy's father. He says he lacks homeowner's insurance, and can't afford to fight the suit. "I've already spent over $4,000 and we haven't even been in a courtroom yet."
