Kenley Jansen allegedly reported to Spring Training in great shape and was promptly anointed as the Dodger’s closer by none other than his manager, Doc Roberts. Yes, Kenley Jansen did not have a great year in 2020, but he did have a good year. If you could throw out two or three bad outings, you might even conclude that Kenley had a great year! But you can’t! It is what is was.
However, there is this: In 2020, batters who faced Kenley Jansen had a 14% hard contact rate against Kenley, which happens to be the lowest in all of baseball.
