The Sox cared enough to bring in a RH hitting OFer.
With Mookie gone for hitters of consequence hitting from the Right side we have JD, Vaz and X....lets see, we have JD, Vaz and X and we have ahhhhhh JD, Vaz and X.
Plus most of a teams power comes from OF or DH bats. MLB has not managed to make agility so meaningless in the infield that you can afford to put too many linebackers in the middle infield and Beni is living proof that there are some hitters that simply can't hit many HR's no matter how much Manfred juices the baseball.
The last time the Sox featured an all LH OF was 1960. We know what a great team that was!
Honestly I don't think the Sox brass cares at least for 2020. They did bring in a RH hitting OFer. He can't hit is weight. But WHO CARES. IMO he is here to keep JD out of the OF. Probably the smartest move they have made so far for 2020.
