sportsfan882 posted that he was getting lineups (before ESPN posts them) from a Nats Twitter.
This site typically lists lineups very early, maybe 4 hours before a game. When Werth got scratched, they posted a second, adjusted lineup to reflect that.
Very good site for planning fantasy team lineups. I've bookmarked it:
