I didn't see the game due to MLB network showing the Dodgers/Padres game, but I saw a couple game plays on the SOX homepage. It looks like the gray pants only have solid black piping now. However, they were wearing the black alternate jerseys which still had the white/gray sleeve trim. I wonder if the road gray jerseys will also just have the black piping on the sleeves. I can't imagine they would have the white/black piping and then not match the pants.
If this is the case, I think they should remove the white/black piping on the sleeves of the black alternates, just like they were when they were originally introduced in 1991. I always thought the black/white trim looked out of place when they wore the black alternates with the home pinstripe pants.
