In my experience, Bluesky doesn't have critical mass yet on a lot of sports content, so I'm sorta not surprised some of the RS Stats content is different. Chad, SoxProspects, Jen McCaffery, PeteAbe, Rob Bradford and a few others in the media have a presence there, but the team itself doesn't yet have an account. I find the same goes for the B's, C's, and Pats. I have my theories on it (more V&Nish), but for better or worse X still remains the primary social media output for quantity.*
*Ironically and apropos of nothing (#RIPCafardo), yesterday's California tsunami warning broke on Bluesky about 15 minutes before X. Go figure.
