Coulombe hails from Scottsdale, Arizona, and attended Chaparral High School, which has produced several notable athletes. His path to professional baseball was fraught with challenges, including a difficult freshman year at the University of Southern California and subsequent injuries that nearly derailed his career. After transferring to Texas Tech, he was drafted by the Los Angeles Dodgers in the 25th round of the 2012 MLB Draft, making his big league debut two years later. Over the past 11 years, he has established himself as a reliable left-handed reliever.

In the 2025 season, Coulombe had a standout performance with the Twins, posting a 1.16 ERA over 31 innings, complemented by 31 strikeouts. However, his time with the Rangers was less successful, where he recorded a 5.25 ERA in 12 innings, allowing three home runs and walking nine batters. Despite these struggles, Coulombe's overall skill set includes a high arm angle and a repertoire of pitches, including a four-seamer, cut/slider, two-seamer, sweeper, and knuckle-curve.

Coulombe's signing is seen as a strategic move to enhance the Red Sox bullpen, which already features dominant closer Aroldis Chapman. His ability to induce weak contact and manage left-handed hitters makes him a valuable addition, particularly in the sixth and seventh innings. The Red Sox aim to diversify their bullpen options, with Coulombe expected to fill critical gaps alongside other left-handed relievers like Jovani Moran and Tyler Samaniego.

Despite his potential, Coulombe's history of injuries raises concerns about his durability. From 2022 to 2025, he averaged only 39 games per season due to various injuries affecting his hips, bicep, elbow, forearm, and shoulder. Critics may question whether his body can withstand the rigors of a full season, especially as he enters the later stages of his career.
