Rafael Soriano, a right-handed pitcher from the Dominican Republic, made his Major League Baseball debut with the Seattle Mariners. Initially signed as an amateur free agent in 1996, Soriano's journey to the majors was marked by his transition from a starting pitcher to a reliever, a role in which he would eventually excel. His early years with the Mariners saw him developing his skills and gaining experience, though his career was briefly interrupted by injuries, including Tommy John surgery in 2004.

After recovering, Soriano returned to the mound with renewed vigor. In 2006, he was traded to the Atlanta Braves, where he began to establish himself as a reliable bullpen option. His time with the Braves was highlighted by his impressive strikeout rates and his ability to close games, earning him the role of closer in 2009. That season, Soriano recorded 27 saves and maintained a low earned run average (ERA), showcasing his ability to handle high-pressure situations.

Soriano's performance caught the attention of the Tampa Bay Rays, who acquired him in a trade before the 2010 season. As the Rays' closer, he delivered one of the best seasons of his career, leading the American League with 45 saves and earning his first All-Star selection. His dominance on the mound was a key factor in the Rays' successful campaign that year, and he finished eighth in the Cy Young Award voting.

Following his standout season with the Rays, Soriano signed a lucrative contract with the New York Yankees in 2011. Initially serving as a setup man for legendary closer Mariano Rivera, Soriano was thrust into the closer role in 2012 after Rivera suffered a season-ending injury. Soriano rose to the occasion, recording 42 saves and helping the Yankees secure a playoff berth. His performance that year was instrumental in maintaining the stability of the Yankees' bullpen.

In 2013, Soriano joined the Washington Nationals, continuing his role as a closer. Over two seasons with the Nationals, he accumulated 75 saves, further solidifying his reputation as a dependable late-inning pitcher. However, his tenure with the Nationals was not without challenges, as he experienced periods of inconsistency, particularly in the latter half of the 2014 season.

Soriano's final stint in Major League Baseball came with the Chicago Cubs in 2015, though his time with the team was brief. After appearing in only a handful of games, he was released, marking the end of his MLB career. Throughout his time in the majors, Soriano was known for his powerful fastball and effective slider, tools that made him a formidable presence on the mound.

Rafael Soriano's career in baseball was characterized by his ability to adapt and excel in various roles within the bullpen.
