Dodgers bolster bullpen depth with call-up of Seth Halvorsen

The Los Angeles Dodgers have reportedly called up reliever Seth Halvorsen from their Triple-A Oklahoma City affiliate, a move designed to strengthen a bullpen that has struggled with consistency. According to a report by The Athletic’s Fabian Ardaya, the team has not yet officially confirmed the transaction, but the acquisition signals a strategic adjustment to manage workload distribution among high-leverage arms.

Halvorsen, 26, was acquired from the Colorado Rockies two weeks prior to the MLB trade deadline while on a minor-league rehabilitation assignment for right shoulder inflammation. The Dodgers’ decision to pursue the reliever appears driven by his velocity; Halvorsen routinely throws a fastball exceeding 100 mph, including a recorded 101 mph pitch. This raw power has historically made teams willing to overlook his control issues, which have resulted in 38 walks in 71 career major league innings.

The call-up comes as the Dodgers seek to protect the efforts of their starting rotation, which holds a 3.54 ERA and ranks second-best in Major League Baseball. Despite the team holding a 7.5-game lead in the NL West with a 70-48 record, the bullpen has posted a collective 4.01 ERA. Manager Dave Roberts is likely looking to utilise Halvorsen in middle innings to preserve his primary relievers, such as Tanner Scott, Alex Vesla, and Jack Dreyer, for late-game situations.

Closer Edwin Díaz has been a particular focal point of concern. Since returning from elbow surgery in April, Díaz has recorded a 10.80 ERA in 10 innings, allowing four runs and six hits in his last five appearances. The move to add Halvorsen does not imply an immediate change in the closer role, given Halvorsen’s history with walks, but rather aims to deepen the roster’s overall resilience.

In his recent stint with Oklahoma City, Halvorsen recorded eight strikeouts in 6 1/3 innings with no runs allowed. He previously posted a 4.74 ERA with the Rockies this season, though he has historically performed better at Coors Field than on the road. The Dodgers’ front office appears to be betting on his velocity to mitigate the risks associated with his command, aiming to stabilise the middle relief corps as the season progresses.
