Despite not being drafted, he signed with the Los Angeles Angels as an undrafted free agent in 2006, beginning his professional career.

O'Day made his MLB debut with the Angels in 2008. As a sidearm pitcher, his unorthodox delivery quickly caught the attention of hitters and fans alike. His time with the Angels was short-lived, as he was claimed off waivers by the New York Mets in 2009. However, his stint with the Mets was brief, and he was soon picked up by the Texas Rangers.

It was with the Rangers that O'Day began to establish himself as a reliable relief pitcher. During his time in Texas, he became an integral part of the bullpen, helping the team reach the World Series in 2010 and 2011. His ability to consistently retire batters with his deceptive delivery made him a valuable asset in high-pressure situations.

In 2012, O'Day's career took another turn when he was claimed off waivers by the Baltimore Orioles. It was in Baltimore that he truly found a home, spending the majority of his career with the team. Over the years, he became one of the most dependable relievers in the Orioles' bullpen, known for his effectiveness against right-handed hitters. His performance earned him an All-Star selection in 2015, a testament to his skill and consistency on the mound.

O'Day's tenure with the Orioles lasted until 2018, when he was traded to the Atlanta Braves. Despite battling injuries during his time with the Braves, he continued to contribute whenever he was on the field. His veteran presence and experience were invaluable to the younger pitchers on the team.

In 2021, O'Day signed with the New York Yankees, adding another chapter to his long career. Although his time with the Yankees was marred by injuries, he remained a respected figure in the clubhouse, known for his professionalism and knowledge of the game.

Throughout his career, Darren O'Day was known for his unique pitching style and ability to adapt to different teams and situations.
