A former personal assistant for Bronson Arroyo secretly sold the Los Angeles Dodgers pitcher's yacht and kept the money, authorities in Florida said on Tuesday. Anthony Acosta, 38, of Tampa was charged with grand theft and forgery and is being held in Hillsborough County Jail on a $50,000 bond, the Florida Department of Law Enforcement said in a statement. Acosta is accused of forging Arroyo's signature on a bill of sale document and selling his 2006 Concept Boat to an unaware buyer in Opa-locka, Florida, pocketing the $22,000 from the transaction in 2013, according to an arrest warrant.
