I wanted to come back to this, because it illustrates how much this is all about what we think we see, rather than necessarily reality. Not a criticism of anybody here, just an observation.
Xander Bogaerts is from Aruba. He's Latino. There currently are 10 Latinos on the 40-man roster, so how would Bogaerts change the optics? Because it's not about what these guys actually are, it's about what somebody perceives them to be?
As others have noted there is a dearth of American-born Black players in MLB, for reasons that are complex, and I only see two players on the Phils roster who might self-classify as African American (Walker and Hall).
But if we're just looking at POC, one of the things I do here is periodically update the banner header, using images of key Phillies players (typically, projected starters and key pitchers). As of now, Edmundo Sosa is the only POC position player in the banner - but three of the five key pitchers are POC; four out of fourteen total, excluding the Phanatic. (I don't have images of Trea Turner or Taijuan Walker - I will only use images of players in Phillies uniforms! I may be able to update the banner if I can get usable images of these two in at least a Phils jersey, from press introductions.)
