He attributes the improvements to swing changes.Refsnyder was terrific last year but it was such a crazy statistical outlier, I'm not really sure we can count on him for much at all.
2016 - .637 ops, 73 ops+
2017 - .463 ops, 25 ops+
2018 - .588 ops, 66 ops+
2019 - nothing
2020 - .498 ops, 40 ops+
2021 - .663 ops, 63 ops+
2022 - .881 ops, 143 ops+
One of these things is not like the others. Like...not even remotely close.
Vs. LHP...
Career - .255/.356/.373/.728
2022 - .359/.411/.594/1.005
I mean, he's definitely okay against lefties, but nothing amazing. I just think it's foolish to consider him a really important piece.
