From "Jerry Sands' debut gives Dodgers a lift" by Tony Jackson at ESPNLosAngeles.com:
While that could have been interpreted as a message -- Lilly (1-2) responded by throwing one behind the Braves' Nate McLouth in the seventh, resulting in a warning being issued to both teams -- Sands was able to shrug it off, especially after Hudson sent an autographed ball to him that included an actual, written message.
"He sent a ball over, which I appreciated, that said, 'It got away from me,' " Sands said. "It's happened before. There is no reason why he would be throwing at my head right there. We had a good at-bat and a good battle after that, and I didn't [read anything] into it at all."
