The Los Angeles Dodgers signed Japanese phenom Roki Sasaki on Friday. The rich could get even richer thanks to a vague MLB rule.

In a move that could shape the future of their rotation and further solidify their global reach, the Dodgers have signed Japanese pitching sensation Roki Sasaki.

And there is opportunity cost involved, because now the Dodgers can't sign a larger pool of international prospects. For this international signing period, all the Dodgers' eggs are in the Roki basket.
