Ryan Feierabend is a former professional baseball player who played as a pitcher. He was born on August 22, 1985, in Cleveland, Ohio. Feierabend began his baseball career in 2003 when he was drafted by the Seattle Mariners in the third round of the Major League Baseball (MLB) draft.

Feierabend spent several years in the minor leagues before making his MLB debut on August 23, 2006, against the Kansas City Royals. He pitched five innings, allowing four runs on six hits and two walks while striking out two batters. Feierabend made a total of 25 appearances for the Mariners in 2006 and 2007, posting a 2-11 record with a 7.22 earned run average (ERA).

Feierabend spent the next few years bouncing between the minor leagues and the majors, playing for the Mariners, the Texas Rangers, and the Toronto Blue Jays. He struggled to find consistency and was often used as a spot starter or long reliever. In 2012, Feierabend signed with the Kia Tigers of the Korean Baseball Organization (KBO) and spent the next six seasons playing in Korea.

Feierabend found success in the KBO, becoming one of the league's top pitchers. He won the league's ERA title in 2017 with a 3.04 ERA and was named to the league's All-Star team in 2018. Feierabend also helped lead the Tigers to the KBO championship in 2017.

In 2019, Feierabend returned to the United States and signed a minor league contract with the Oakland Athletics. He made two appearances for the Athletics in May 2019 before being designated for assignment and eventually released. Feierabend then signed with the Sugar Land Skeeters of the independent Atlantic League of Professional Baseball, where he finished the season.

Overall, Feierabend's baseball career was marked by ups and downs. He struggled to find success in the majors but found a home in the KBO, where he became a star pitcher. Despite his success in Korea, Feierabend was never able to establish himself as a consistent major league pitcher.
