Drew Pomeranz, a left-handed pitcher, began his Major League Baseball career after being selected fifth overall in the 2010 MLB Draft by the Cleveland Indians. However, his journey in the majors started with the Colorado Rockies, who acquired him in a trade in 2011. Pomeranz made his MLB debut with the Rockies in September of that year, showcasing his potential as a starting pitcher.

In Colorado, Pomeranz spent parts of three seasons, where he experienced the challenges of pitching at Coors Field, a venue notorious for being tough on pitchers due to its high altitude. Despite these challenges, he demonstrated flashes of brilliance, but consistency eluded him during his tenure with the Rockies.

A trade to the Oakland Athletics in 2013 marked a new chapter in Pomeranz's career. With the Athletics, he transitioned between starting and relieving roles, which allowed him to refine his skills and adapt to different pitching situations. His time in Oakland was marked by steady improvement, and he became a valuable asset to the team's pitching staff.

In 2016, Pomeranz's career took another turn when he was traded to the San Diego Padres. It was with the Padres that he truly began to shine, earning his first All-Star selection that year. His performance in the first half of the season, characterized by a low ERA and high strikeout rate, caught the attention of the Boston Red Sox, who acquired him in a mid-season trade.

Pomeranz's stint with the Red Sox was highlighted by a strong 2017 season, during which he won 17 games and played a crucial role in the team's rotation. His efforts helped Boston secure a division title, and he was a reliable starter throughout the season. However, injuries and inconsistency affected his performance in 2018, limiting his contributions during the Red Sox's World Series-winning campaign.

Following his time in Boston, Pomeranz returned to the National League, signing with the San Francisco Giants in 2019. His tenure with the Giants was short-lived, as he was traded back to the Milwaukee Brewers later that year. With the Brewers, Pomeranz transitioned to a bullpen role, where he excelled as a late-inning reliever, showcasing his ability to adapt and thrive in different pitching roles.

In 2020, Pomeranz returned to the Padres, signing a four-year contract. As a reliever, he continued to perform well, providing the Padres with a reliable option out of the bullpen. His experience and adaptability made him a valuable member of the Padres' pitching staff, contributing to the team's success during the shortened 2020 season.
