I'm all for getting him. I'm saying I don 't expect him to repeat his 0.900 WHIP over the next 30 IP. Saying that does not mean I think he will suck or is not worth trading for.
It's his great numbers now that is sparkling and getting everyone's attention. His career numbers are fine, but not great, and not "nails." 19 IP from 2019-2021 is far from nails.
WHIP
1.157 NYY decent
1.107 CWS good
1.250 TBR meh
2.100 PHI yuck
0.900 Cubs in 30 IP
.608 OPS Against Career is very good.
.484 OPSA in 2022 is probably not sustainable, but again, I think the hot hand theory has merit, and I'm all for getting him. I'll take .608 and 1.145 over the second half of 2022. Our pen, this year, as a whole is .665 and 1.233.
Robertson looks like a clear improvement.
