Nationals signed LHP Zach Penrod to a minor league contract with an invitation to spring training.
Penrod pitched his way to the majors in 2024, making seven appearances out of the Boston bullpen, but he was a mess last year, finishing with a 7.83 ERA in six starts and 20 relief appearances in the minors for the Red Sox and Dodgers. He walked a total of 67 batters in 33 1/3 innings. He’ll almost certainly have to prove something in Triple-A before getting another chance.
