FRIDAY: Atlanta has released Venters, per the MLB.com transactions page.

WEDNESDAY: The Braves have designated left-hander Jonny Venters and infielder Ramiro Pena for assignment, according to the team’s transactions page. Additionally, the team has added Brandon Cunniff, Yean Carlos Gil, Kyle Kubitza, Williams Perez, Mauricio Cabrera and top prospect Jose Peraza to the 40-man roster to protect them from the Rule 5 Draft.

The 29-year-old Venters was an elite setup man with Atlanta from 2010-12 but underwent Tommy John surgery — the second of his career — that kept him out for all of the 2013 season. Venters rehabbed the injury through August of this season before learning that he had re-torn the ligament. In September, MLB.com’s Mark Bowman reported that Venters would undergo a third Tommy John and attempt to make a comeback. Venters has a 2.23 ERA in three career seasons to go along with an average of 10.1 strikeouts and 4.3 walks per nine innings pitched.

Pena, 29, batted .245/.304/.347 in 165 plate appearances for the Braves this season — a decline from the .278/.330/.443 line he posted in 107 PA the previous year. Pena has more than four years of big league service as a utility player with the Yankees and Braves. He’s a career .244/.288/.330 hitter in 610 PAs at the big league level.

Both Venters and Pena were arbitration eligible. Venters would have earned either the same $1.6MM he made in 2014 or slightly less, had he gone through arb, while MLBTR contributor Matt Swartz projected Pena to earn $900K.
