According to Japan's Sports Hochi, via Patrick Newman of NPB Tracker, the Yankees had three scouts on hand to watch Yu Darvish pitch Friday night. Darvish didn't dominate, but he held the opposition to one earned run on four hits and fanned four batters.
We've covered Darvish at length here at MLBTR. He won't be a free agent until 2014, but he's only 22 and already has multiple major league teams tracking his progress.
