Kolby Allard
Many remember Kolby Allard's first stint with the Braves as he was their first round pick back in 2015. After a pretty quick ascent through the minor leagues, Kolby wasn't able to solidify a spot in the Braves rotation and ended up getting traded to the Rangers in the deal that brought Chris Martin to Atlanta in 2019.
However, Kolby would make his return to Atlanta when the Braves mercifully sent Jake Odorizzi out of town. After starting the season on the IL with an oblique injury, he would go on to make a handful of appearances for the Braves this season and ended up with a 6.57 ERA after his last couple of games went rather poorly.
Kolby is only just hitting arbitration and there is a chance that the Braves go ahead and keep him around given how cheap he will likely be, but the bigger problem is that Kolby isn't healthy right now. In July, the Braves placed him on the 60 day IL with nerve inflammation in his throwing shoulder which is never good news. At this point, it is hard to see him getting tendered a big league contract, although bringing him back on a minor league deal could make some sense.
