I was listening to the SoxProspects pod over the weekend, and there was a bit about Yoshida that was interesting.
Apparently, the way that UZR or fWAR is constructed (I forget which) penalizes Fenway left fielders. Essentially fly balls that go off the monster for a hit that would be caught in other ballparks are counted as a negative for the left fielder. If there is a sky high flyball that travels 325 ft in the air and hits right above the AL east scoreboard, it is a ding against the fielder since that ball is caught the majority of the time.
He isn't Andruw Jones out there obviously, but it feels like the fielding analytics may not tell the full story.
Anyways I think the guy was physically and mentally gassed by the all-star break. He hadn't seen his newborn child and wife all season, and was playing in multiple different time zones for the first time in his career. The optimistic fan side of my brain hopes that he has a Seiya Suzuki-like bounce back season in '24, granted Masa is about 2 years older. Suzuki improved in most offensive metrics in his 2nd big league season
