Mario Ramos was drafted by the Kansas City Royals in the 48th round (1399th overall) of the 1996 amateur draft. He decided not to sign and continued to pitch for Rice University. In the 1998 Baseball World Cup, Ramos allowed 3 runs in 2 1/3 innings of relief. In 1999, he was drafted by the Oakland Athletics in the 6th round (183rd); this time he signed.
In 2000 and 2001, he had a combined 30-9 record in the minors. On January 14, 2002, he was traded to the Texas Rangers along with Jason Hart, Gerald Laird and Ryan Ludwick for Carlos Pena and Mike Venafro.
From 2002 to 2003, his winning percentage dropped to .379 (11-18 record). That trade, it seems, had a very bad effect on his career. Even though he had a mediocre (at best) season in the minors in 2003, he was still called up to the Rangers. On June 19th, he made his major league debut.
At the end of 2003, he was selected off waivers from the Rangers by the team who drafted him, the Oakland Athletics. Even though he was rumored to be part of a deal being concocted between the Athletics and the Los Angeles Dodgers for Milton Bradley, he was not the one who ended up being traded, and remained in the Athletics' farm system.
In 2006, he was with the San Diego Padres in their system. He was back in the Athletics system in 2007.
