The Los Angeles Dodgers have added reliever Seth Halvorsen to their major league roster in an effort to strengthen a struggling bullpen. The 26-year-old right-hander was called up from Triple-A Oklahoma City on Monday, less than a month after being acquired from the Colorado Rockies in a trade.

Halvorsen, known for a fastball that can reach over 100 mph, had been sidelined with shoulder inflammation since late June while with the Rockies. Prior to his injury, he posted a 4.74 ERA in 21 appearances this season. Over the course of his three MLB seasons, he holds a 4.31 ERA with 66 strikeouts across 71 innings pitched.

The trade sending Halvorsen to the Dodgers occurred two weeks before the July 31 trade deadline, with Los Angeles sending pitching prospect Nick Frasso and outfielder Landyn Vidourek to Colorado. Since joining the Dodgers’ organization, Halvorsen has made a strong impression at the Triple-A level, delivering six scoreless innings and striking out eight of the 25 batters he faced.

Los Angeles’s bullpen has struggled this season, with key right-handers Edwin Díaz and Evan Phillips both experiencing difficulties as they returned from injuries. Additional veteran relievers, including Blake Treinen and Brock Stewart, remain unavailable due to injuries, increasing the need for reinforcements.

Halvorsen’s promotion aims to provide the Dodgers with fresh arms as they navigate the late stages of the season and seek to stabilize their relief pitching staff.
