Bajenaru began his college career at the Riverside Community College. The Oakland Athletics drafted him in the 13th round after his sophomore season, but he elected not to sign. He parlayed his community college performance into a scholarship at the University of Oklahoma. The Chicago White Sox chose him in the 36th round the next year, but he again returned to school. In 2000, he was a third-team college All American as a utility player, and he made the Big 12 Conference All-Star team as an outfielder. He was projected to be taken between the second and fifth rounds of the 2001 draft by Baseball America, but signed with the White Sox as a non-drafted free agent in March, before the draft was held.
Bajenaru has generally worked as a closer during his minor league career, striking out more than 10 batters per nine innings, and collecting 24 wins and 91 saves in relief. He missed the entire 2002 season as a result of Tommy John surgery, but recovered well and was able to resume his baseball career in 2003.
Bajenaru made his major league debut with the White Sox on September 4, 2004. After brief stints in their bullpen in 2004 and 2005, he was traded to the Diamondbacks on March 8, 2006, with the White Sox receiving infielder Alex Cintron.
