WASHINGTON -- Left-handed reliever Dario Alvarez was claimed off waivers by the Atlanta Braves on Wednesday.

Alvarez had been designated for assignment by the New York Mets on Monday when they needed to create a 40-man roster spot for the promotion of utility player Ty Kelly once Lucas Duda landed on the disabled list.

Alvarez, 27, was 0-1 with a 9.98 ERA in 17 relief appearances for Triple-A Las Vegas this season. He made a combined 10 relief appearances with the Mets in 2014 and '15.
