Andrew Chafin has long been considered one of Major League Baseball's most reliable left-handed relievers. In May 2025, he made headlines by signing a major league contract with the Washington Nationals. This move signals a new chapter in Chafin’s career and has significant implications for both him and his new team. In this article, we break down Chafin’s MLB journey, analyze his recent performance, and explore what his arrival means for the Nationals’ bullpen.

A Veteran Presence: Chafin’s Path to Washington

Chafin's career is marked by consistency and adaptability. The veteran reliever has pitched over a decade in the big leagues, compiling more than 500 innings and maintaining a career ERA just over 3.40. His most recent outings with the Detroit Tigers and Texas Rangers showcased his ability to make an impact wherever he lands.

In 2024, Andrew Chafin was one of the Tigers’ most effective arms, posting a solid 3.16 ERA with 50 strikeouts over 37 innings before being traded to the Rangers. Yet, his time in Texas proved more challenging, with control issues hampering his performance. After the season, Chafin found himself back in free agency, ultimately signing a minor-league deal with Detroit.

Signing with the Nationals: Details of the Deal

Chafin’s consistent minor league performance in 2025—featuring a 2.13 ERA and strong strikeout rates—caught the attention of the Nationals. The club, seeking to strengthen a struggling bullpen, inked him to a one-year major league deal guaranteeing $1 million. To make room for Chafin, the Nationals designated lefty Colin Poche for assignment. This signing is expected to provide much-needed stability and veteran versatility to Washington’s relief corps.

Chafin’s Recent Performance and Expectations

Chafin’s stats back up his veteran status: since 2017, he’s made more MLB relief appearances than any other arm. In 2024, he posted a 3.51 ERA across 62 outings, with impressive strikeout numbers despite a higher-than-ideal walk rate. Even though he had to settle for a minor league deal this year, Chafin’s performance in Triple-A suggested he was ready for another big-league opportunity.

According to ESPN’s report on the signing, the Nationals hope Chafin’s presence can turn around what has so far been a struggling bullpen. If he continues his usual form, Chafin could become a key trade asset later in the season or help anchor the Nationals’ relief staff.

What This Move Means for the Nationals

For Washington, adding an experienced left-hander like Andrew Chafin offers an immediate upgrade. The team has tried several relievers this season, but consistent results have been elusive. A proven veteran allows the Nationals both flexibility and credibility as they navigate a challenging NL East.

Chafin brings a wealth of experience and a track record of success, making him a valuable addition. His ability to get big outs in crucial moments could also help mentor the younger arms in Washington’s bullpen. Should he perform well, the Nationals might consider keeping him beyond 2025, or he could fetch value in a trade as contenders look to shore up their relief pitching later in the year.

Conclusion: Andrew Chafin’s Fresh Start

Andrew Chafin’s signing with the Nationals is more than just another transaction. It represents a fresh start for a veteran reliever who thrives on challenges and change. With his skill set and experience, Chafin is poised to make an impact in Washington—both on the field and in the clubhouse. Nationals fans should keep an eye on his performance as the season unfolds; it could be a turning point for both the player and the team.
