Here is Ian Browne's mlb.com piece:

My two cents:
Hensley Meulens seems to me like he'd be a very good quick emergency hire given the time of year, just hired as the bench coach for the Mets in late November, but has been barely passed over for a bunch of jobs the last couple of seasons and would likely jump at the chance. As Browne says, he was the runner-up for the NY job and speaks five languages (English, Spanish, Dutch, Papiamento and Japanese), he prepared as Bochy's successor in SF for years and then was passed over for Zaidi's binkie Gabe Kapler. He is a guy dying for a shot and could probably be hired on favorable terms for BOS, maybe a one year deal with a team option at the end of 2020 to extend it through 2022.
Also this one has the added bonus of grabbing Meulens before the Mets inevitably fire Beltran even though then they will hire Hinch anyway (for 2021 and onward).
(I believe I was the first to mention Chaim in the GM thread, let's see if another educated guess from an obsessed observer hits)
