Ray's ERA over the years is quite the journey:
2014: 8.16
2015: 3.52
2016: 4.90
2017: 2.89
2018: 3.93
2019: 4.34
2020: 6.62
2021: 2.84
Prior to this year, he had never thrown more than 175 innings in a season, this was the one year where he finally put it together with 193.1 IP.
Still the right move (and an absolute steal) trading him for Fister (who posted a 2.41 ERA in 164 IP and a 16-6 record in 2014)
