I hadn't considered this but that makes a lot of sense. It must have been very isolating for Javy to be on the team last year as the only high dollar veteran guy, outside of Kenta Maeda who is both not Latin and not a hitter. Having a veteran on the team from that part of the world who produces at the plates and, bonus, Javy can bond with, could conceivably lead to both guys optimizing their performance.
I know nothing about whether they actually are bonding like that, so it's all hypothetical to me. But it makes sense.
