The Nationals selected Garrett's contract from Triple-A Rochester on Tuesday.

Garrett gets his first call to the big leagues since 2019, when he made 13 appearances out of Detroit's bullpen. He was rewarded with the promotion after turning in a 4.00 ERA, 1.22 WHIP and 25:10 K:BB across 27 innings at Rochester. Garrett's initial usage will likely be limited to lower-leverage scenarios.
