Actually, by the time they met with Congero, baseball investigators already had fielded several reports about a gambler named Hunter who claimed to be fixing games with Jeff Locke -- and they were taking the allegations seriously. An early tip came in an anonymous letter routed to MLB’s department of investigations. The unit was set up in 2008 in response to criticism that the sport had been lax in policing steroid abuse.
