The ASG above all is the sport's regular season sponsor showcase. For that reason, the fan vote is fine - and breaking ties with marketability/reputation is fine too. A minor quibble is that ASG is a contract incentive so you'd like the choices to be sound - but that's fairly minor.
For the Sox, the astonishing stat is (by fWAR), 6 of their 8 regulars are in the Top 20 in the AL ... (Bogaerts, Shaw, Ortiz, Bradley, Betts, Pedroia). Bogaerts in particular is a completely reasonable MVP choice for the first quarter of the season.
Pedroia is part of a heck of a senior citizen revival at 2B behind Altuve (Cano having his best SEA season, Kinsler geting in the wayback machine)
