Thomas Andrew Pomeranz Bio
Thomas Andrew Pomeranz, nicknamed Big Smooth, is an American professional baseball pitcher currently with the Los Angeles Angels. A veteran of Major League Baseball since 2011, Pomeranz is an MLB All-Star (2016) and earned a World Series ring with the Boston Red Sox in 2018.
Early Life and Background
Thomas Andrew Pomeranz was born on November 22, 1988, in Collierville, Tennessee. He grew up in the Memphis area and developed as a baseball prospect through his high school years before electing to play college baseball.
Pomeranz declined to sign after being selected in the 2007 draft and enrolled at the University of Mississippi, where he refined his pitching and gained national attention as a collegiate prospect. His college performance set the stage for his selection in the first round of the 2010 Major League Baseball draft by the Cleveland Indians.
Path to Baseball
Pomeranz rose through amateur and collegiate ranks as a polished left-handed pitcher known for a strong curveball and strikeout ability. He pitched for the United States Collegiate National Team and led the team with strikeouts in the 2009 World Baseball Challenge, building a resume that helped him become a top college arm in 2010.
Following the 2010 draft, Pomeranz signed with the Cleveland Indians and entered professional baseball, joining the Indians’ minor-league system before being involved in trade activity that brought him to the Colorado Rockies organization in 2011. Those early professional moves accelerated his path to the major leagues.
Thomas Andrew Pomeranz Career
Early Career (2011–2013)
Pomeranz made his Major League debut with the Colorado Rockies on September 11, 2011, starting against the Cincinnati Reds and recording five scoreless innings in his first big-league outing. He split time between Triple-A and the Rockies rotation through the 2012 season and made multiple starts in 2011 and 2012 as a developing left-handed starter.
After limited appearances for Colorado in 2013, Pomeranz was traded to the Oakland Athletics in December 2013, beginning the next phase of his career that featured both bullpen and rotation work and showcased his ability to adapt roles.
Oakland Athletics Breakthrough (2014–2015)
With the Oakland Athletics in 2014, Pomeranz began the season in the bullpen before moving into the starting rotation in May. He posted strong results in a stretch as a starter, delivering multiple outings without allowing a run and recording a career-low ERA in one season with the Athletics while demonstrating the command that made him a multi-inning option.
During 2015 Pomeranz shifted between relief and spot starts, appearing in a career-high number of games while recording several saves and maintaining versatility. His 2014–2015 tenure with Oakland established him as a reliable left-handed arm capable of filling multiple roles for a major-league staff.
San Diego Padres Breakthrough (2016)
Pomeranz joined the San Diego Padres early in 2016 and earned a role in the starting rotation after requesting an opportunity to start. He produced an exceptional first half of the season, posting a sub-3.00 ERA and limiting opposing batting average, results that led to his selection to the 2016 MLB All-Star Game.
His All-Star season in 2016 raised his profile around the league and prompted further trade interest, culminating in a midseason move that carried him to a new organization with postseason aspirations.
Boston Red Sox Era (2016–2018)
Traded to the Boston Red Sox during the 2016 All-Star break, Pomeranz finished the year in Boston and then moved into a full-time starting role in 2017. The 2017 season was a personal high point: Pomeranz worked to a 17–6 record with a sub-3.50 ERA and registered a career-high number of strikeouts, serving as a key member of the Red Sox rotation that season.
In 2018 Pomeranz dealt with injuries and transitioned back to a bullpen role. He was added to Boston’s postseason roster and earned a World Series championship when the Red Sox defeated the Los Angeles Dodgers in 2018, becoming a World Series champion that fall despite limited postseason appearances.
Later Career and Return Stints (2019–2021)
Pomeranz signed with the San Francisco Giants for 2019 before being traded to the Milwaukee Brewers midseason. He later rejoined the San Diego Padres on a multiyear deal beginning in 2020 and contributed effectively out of the bullpen through 2021, posting a low ERA in relief work before undergoing season-ending surgery to repair a torn flexor tendon.
Injuries limited Pomeranz’s availability in subsequent seasons; he missed significant time while rehabbing left elbow and flexor tendon procedures and did not appear for San Diego in 2022 or 2023 as he recovered from surgery and rehabilitation setbacks.
Chicago Cubs and Los Angeles Angels Era (2025–Present)
In 2025 Pomeranz joined the Chicago Cubs organization and performed strongly out of the bullpen, making a substantial number of appearances with a low earned run average and contributing key innings. His 2025 work out of the Cubs’ bullpen demonstrated successful recovery and a return to dependable relief performance at the major-league level.
Following the 2025 season, Pomeranz signed a one-year major-league contract with the Los Angeles Angels beginning in 2026. That agreement marked his most recent team move and continued his role as a veteran left-handed reliever for a major-league bullpen staff.
