One of those ones that is hard to evaluate with WAR because Atlanta cared more about getting someone they thought was a good bet to be positive value while CHW just cared about sorting through a bunch of players that would probably suck as they try to find one or two decent keepers.
Bummer - 0.2 WAR in 15.2 innings
Shuster - 0.2 WAR in 18 innings
Soroka - horrendous
Shewmake - horrendous
Nicky Lopez - horrendous
Riley Gowens - good numbers in A+
So you could say it looks like a good one for CHW. They get Shuster, who seems to be an MLB arm and he is pre-arb, along with a so-so prospect in Gowens.
Bummer has options after this year but at $7M they aren't really worth anything.
Lopez, Soroka, Shewmake --- possibly irrelevant and will only stick on the Chicago 40 man if they fail to find viable alternatives. But I guess they have all year to continue working with Soroka. His 93 stuff+ is close enough to viable that maybe if he at some point finds average command, he could piece it together as an SP5. There are worthwhile SP5s with worse stuff+ numbers than 93.
