The Nationals claimed Varland (undisclosed) off waivers from the Diamondbacks on Thursday, Chris Cotillo of MassLive.com reports.
Varland didn't pitch during the final three months of the 2025 season due to an undisclosed injury, and it's unclear what his current health status is. The right-handed reliever has collected a 4.82 ERA and 47:24 K:BB across 46.2 frames covering parts of two major-league seasons.
