Myers was never great. He's never been over .797. He hasn't really declined all that much.
Here's some different breakdowns of his career:
.759 first 4 years (1663 PAs)
.768 last 3 years (1482 PAs)
.734 first 3 years (987 PAs)
.795 middle 2 year (1325 PAs)
.749 last 2 years (833 PAs)
Here's what Myers is a plus:
vs LHPs
.877 in 2019 (104 PAs)
.805 in 2018 (141 PAs)
.790 in 2017 (172 PAs)
.814 in 2016 (163 PAs)
Yes, Mike Lowell had just one bad year, but it was worse than any season Myers has had in a long time.
.658 in 2005.
Maybe Bloom know something about Myers and thinks he can get him to hit more like .795 than .749, but to me, it's all about his production vs LHPs and our ability to add a young player.
