At age 18, Cordero was drafted by the San Diego Padres in the 26th round of the 200 MLB draft, but he chose to enroll at Cal State Fullerton, where he was a standout reliever. With an ERA of under 1.83 he made the 1st team All-America Freshman team and was selected to the Big West All-Conference team, the latter of which he repeated in each of his next two years. In, he was the Fullerton Regional MVP, and then was drafted by the Expos in the 1st round.
Pro career
First two years
Cordero pitched briefly in 2003, and then appeared in 69 games for the Expos in, compiling an ERA of 2.94, usually appearing as a closer. He earned a save in the last Montreal Expo victory in Hiram Bithorn Stadium on July 11, 2004. He also threw the final pitch for the Expos at Olympic Stadium on September 29, 2004 and the final pitch for a win on October 2 against the New York Mets at Shea Stadium.
2005
The Expos became the Washington Nationals in 2005, and Cordero had a career-best season. In June 2005, Cordero tied the major league record for saves in one month with 15. He shares the record with Lee Smith and John Wetteland. He also converted his 24th consecutive save, breaking the club record held by Mel Rojas. On September 9, 2005, Cordero's 44th save broke the franchise record. He completed the 2005 season with 47 saves, leading the major leagues, and was selected to the National League pitching staff for the 2005 MLB All-Star game, facing one batter, Iván Rodríguez, and striking him out. He was the 2005 Washington Nationals Player of the Year, and won the National League Rolaids Relief Man of the Year Award.
2006
In February, Cordero and his teammate Brian Schneider were chosen to play for Team USA in the World Baseball Classic. During the season, however, his production tailed off. While he still got 29 saves, his ERA went from 1.82 to 3.19.
2007
In the beginning of the season, Cordero faced a tough time against batters. By May 6, his ERA was 4.70. Cordero admitted he was distracted by the illness of his ailing grandmother, and missed six games for personal bereavement leave. He came back a changed man, and starting May 16 made 12 consecutive appearances without allowing a run. On June 13, Cordero became the second youngest player in baseball history to reach 100 saves in a career. Echoing his final pitches at Olympic Stadium and Hiram Bithorn Stadium in 2004 Cordero closed out the final Nationals game at RFK stadium getting a save on September 23, 2007. He is likely the only pitcher in major league history to throw the final pitch at three different home stadiums for the same franchise.
2008–2011
Cordero missed almost all of the season after undergoing surgery to repair a labrum tear, an injury he suffered in April. On October 30, 2008 the Nationals sent him outright to AAA Syracuse, and he rejected the assignment, becoming a free agent. Among other reasons for Cordero's rejection was that he was displeased with how he found out that he would be "non-tendered" by the Nationals at the end of the season—via an impromptu comment made by Nationals' GM Jim Bowden on a radio show in July. On March 12, 2009, Cordero signed a minor league contract with the Seattle Mariners with an invitation to spring training. He was to compete for the closer role once he fully recovered from surgery, but was unable to make a minor league appearance until July. He was called up to the Mariners on June 3, 2010, taking the spot of the retired Ken Griffey, Jr. On July 15, 2010 he refused a minor league assignment from the Seattle Mariners and became a free agent. On July 21, 2010 Cordero agreed on a minor league deal with the New York Mets and was assigned to Triple A Buffalo. On January 3, 2011, Cordero signed a minor league contract with an invite to spring training with the Toronto Blue Jays. He was released on May 17. Cordero later signed with the St. Paul Saints of the American Association of Independent Professional Baseball, but retired on June 20, 2011. On February 13, 2013, Cordero signed a minor league contract with the Los Angeles Angels of Anaheim due to his desire to play again. He was assigned to the Inland Empire 66ers of the California League, the Class-A affiliate of the Angels, to begin the season.
Personal life
Cordero has two children: Riley and Tehya. Tehya died of Sudden Infant Death Syndrome. He was married to Jaime Cordero but the couple is now separated.
