I'm surprised how many Brewers fans I've seen shocked at how good Ashby looked today. He didn't look this good in his first two outings but this is pretty much exactly what he looked like the last 5 weeks of the season last year when he was one of the best relievers in MLB.
These were his numbers post being called up in late August:
19.2 IP, 1.37 ERA, 0.78 FIP, 1.70 xFIP, 37% K-rate, 4% BB-rate, 51% GB-rate
