Unlikely on Turang as he is not on the 40-man roster. Ruiz is more likely to be added to the roster but I think the Brewers just call up a bunch of relievers instead as that is what the Brewers need right now. This would put the Brewers at the maximum of 14 pitchers.
So I believe two of Cousins, Perdomo, Topa, Kelley or Small will be brought back up. Once Gott is healthy he will replace one of those players on the list.
