Yes, I was speaking more to the Kimbrel of 2018, especially the playoffs.
He had off the charts numbers with ATL and in BOS in 2017. His o.995 WHIP in 2018 was very good and only slightly over his career 0.929 mark.
It's always been the BBs. His career H/9 is an amazing 4.8- almost 1 every 2 innings! His BB/9 is 3.5, but was 5.1, 1.8 and 4.5 in his 3 years with BOS.
His playoff WHIP is 1.258 which is fed by a 5.2 BB/9 rate. His last 4 playoff series with the Sox, it was:
2.500
1.714
2.000
1.154
(In 12.2 IP: 8 ERs, 9 BB, 13 H, 2 WPs, & 2 HRs)
