From the Post:
The next milepost in this saga: Opening Day. Major league players don’t receive their salaries until the regular season begins. If a compromise isn’t worked out, the Nats could place Strasburg on the restricted list — which would mean they wouldn’t have to pay him unless and until he reported.
No chance Boras allows the Nats to even be in the position to legally withhold payment. My guess is that Stras will show up unannounced at Nats Park sometime between the futures game and opening day.
