The Braves have designated right-hander Luke Jackson for assignment, David O’Brien of the Atlanta Journal-Constitution tweets. His spot on the Braves’ 25-man roster will go to righty Lucas Sims, whom they recalled from Triple-A.
This is the second time since last December that the Braves have designated the 26-year-old Jackson, who rejoined their 40-man roster when they selected his contract April 4. Jackson then went on to make only two appearances, during which he combined for 1 1/3 innings and gave up two earned runs on two hits and a walk. He yielded both of those earned runs as part of the Braves’ epic collapse Saturday against the Cubs, who rallied back from a 10-2 deficit to escape with a 14-10 win.
Sims, 23, has been a well-regarded prospect at times since Atlanta chose him 21st overall in the 2012 draft. He struggled during his first major league promotion last season, though, with a 5.62 ERA/5.07 FIP across 57 2/3 innings (14 appearances, 10 starts).
