The Dodgers acquired Kmatz and catcher Hunter Feduccia from the Rays on Monday in exchange for Jack Suwinksi and international bonus pool space.
A 23-year-old righty reliever, Kmatz had a 2.89 ERA, 0.92 WHIP and 74:10 K:BB in 53 innings at Double-A Montgomery this season. Kmatz will likely report to the Dodgers' Double-A affiliate in Tulsa.
