Well, we just don't have enough pitchers left.
The reason Alvarez was in the game last night was because Smith was hurt and is on the DL again.
We've lost our number one and two starters, we played an extended time without our closer and our set up guy has returned to the DL a second time. And Trop is also out, Simmons is out our back up SS is out etc.
Wilson hasn't been able to return, Skaggs hasn't either. There aren't any arms left.
