I don't know, but I checked Boyd's stats, after he came back from the IL on 6/25. At the same time, I also checked other SPs, during the same period, Shota was our best pitcher over the last 30+ days.
ERA: 1.55
xERA: 3.36
FIP: 2.90
xFIP: 3.63
K/9: 7.76
BB/9: 1.86
HR/9: 0.62
For every single stat (listed above), Shota was the #1 on the team.
