The Braves re-signed veteran reliever Rex Brothers to a one-year deal Thursday, avoiding arbitration with the left-hander before Friday’s deadline to offer contracts to unsigned players or make them non-tendered free agents. It’s a split contract worth $1.1 million if he makes the major league team and $450,000 if he’s in Triple-A, with only the latter amount guaranteed. He has a minor league option left, so he could go back and forth between the majors and minors in 2018 without being exposed to waivers. Brothers, who’ll be 30 on Dec. 18, posted a 7.23 ERA in 27 appearances for the Braves in a comeback season after being called up in late June from Triple-A. He had 33 strikeouts with 12 walks in 23 2/3 innings, the highest K rate among Braves pitchers with at least 20 appearances. The former Rockies closer worked primarily in middle relief for the Braves and limited left-handed batters to a .216 average and .644 OPS in 41 plate appearances, while right-handers hit .273 with an .848 OPS in 64 PAs. Teams face an 8 p.m. deadline Friday to tender contracts to players and the Braves have seven remaining unsigned arbitration-eligibles: first baseman/pinch-hitter Matt Adams; starting pitcher Mike Foltynewicz; relievers Arodys Vizcaino, Sam Freeman and Dan Winkler, and utility men Danny Santana and Jace Peterson. Brothers became arbitration-eligible after the Braves declined a 2018 option on his contract.
