Anthony Swarzak's journey through Major League Baseball is a tale of perseverance and adaptability. Born on September 10, 1985, in Fort Lauderdale, Florida, Swarzak's professional career began when he was drafted by the Minnesota Twins in the second round of the 2004 MLB Draft. His early years in the minor leagues were marked by steady development, and he eventually made his MLB debut with the Twins on May 23, 2009.

Swarzak's tenure with the Twins saw him oscillate between the starting rotation and the bullpen, a testament to his flexibility as a pitcher. In his rookie season, he started 12 games, posting a 6-4 record with a 6.25 ERA. Over the next few years, he continued to refine his skills, primarily serving as a long reliever and spot starter. His time with the Twins was characterized by a willingness to fill various roles, which proved valuable for the team.

After his stint with the Twins, Swarzak signed a minor league contract with the Cleveland Indians in 2015. Although his time with the Indians was brief, it provided him with an opportunity to showcase his abilities in a new environment. Later that year, he joined the New York Yankees, where he continued to work out of the bullpen. His performance with the Yankees was solid, as he maintained a 3.38 ERA over 10 appearances.

The following year, Swarzak signed with the Chicago White Sox, where he enjoyed one of the best seasons of his career. In 2017, he posted a 2.23 ERA over 48 appearances, demonstrating his effectiveness as a reliever. His success with the White Sox led to a mid-season trade to the Milwaukee Brewers, where he continued to excel, helping the team in their playoff push.

Swarzak's career took another turn in 2018 when he signed a two-year contract with the New York Mets. Unfortunately, his time with the Mets was marred by injuries, limiting his effectiveness and availability. Despite these setbacks, he remained a valuable presence in the bullpen when healthy.

In 2019, Swarzak was traded to the Seattle Mariners as part of a multi-player deal. His tenure with the Mariners was short-lived, as he was traded again mid-season to the Atlanta Braves. With the Braves, he found a resurgence, posting a 4.31 ERA over 44 appearances and playing a role in their bullpen during their playoff run.

Swarzak's career continued with brief stints with the Philadelphia Phillies and Arizona Diamondbacks, as well as a return to the Kansas City Royals. Throughout his career, he was known for his fastball-slider combination, which he used effectively against both right-handed and left-handed hitters.

Off the field, Swarzak was recognized for his professionalism and work ethic, earning the respect of teammates and coaches alike. His ability to adapt to different roles and teams was a hallmark of his career, allowing him to extend his time in the majors over more than a decade.

In 2021, Swarzak signed a minor league deal with the Kansas City Royals, marking the final chapter of his professional playing career.
