It's international free agent signing day in Major League Baseball. Today is the day when the window to officially sign international free agents opens, and as a result, many talented young prospects have formally signed deals with the MLB organizations that they have already agreed to join once they were a certain age. The prospects who are at least 16 years old and will turn 17 before September 1 of this year are eligible to officially put pen to paper and start competing for their respective MLB team's minor league affiliates.
The only comparable day in regard to MLB teams adding this much talent to their farm system at once is the MLB Draft, which now takes place in early July.
