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

A former MLB exec is confident teams like the New York Yankees or Mets will push for an investigation of how the Dodgers signed Roki Sasaki.

Japanese ace Roki Sasaki announced his intention to sign with the Los Angeles Dodgers, choosing the defending World Series champions over the San Diego Padres and Toronto Blue Jays, among other teams who showed interest in obtaining his services.
