He played in Major League Baseball (MLB) for the Cleveland Indians, Washington Nationals, New York Yankees, and Boston Red Sox.

Traber attended Loyola Marymount University, where he was First-Team All-American and West Coast Conference Player of the Year.

[2] In 2001, the Mets traded Traber to the Cleveland Indians along with Matt Lawton, Alex Escobar, Earl Snyder, and Jerrod Riggan for Roberto Alomar, Mike Bacsik, and Danny Peoples.

[4] Although he started out well (1.59 ERA, 1-0 record in seven games that spring)—even pitching a one-hit shutout of the New York Yankees on July 8—Traber's season fell apart when elbow problems that haunted him in college and the minors came back to end his '03 campaign and ultimately the entire 2004 season when he needed Tommy John surgery.

[10] In December 2008, he signed a minor league contract with an invitation to spring training to return to the Red Sox.
