Because Sasaki is beholden to the rules of the international signing period and bonus pools, there is a more level playing field than for other free agent signings. It’s been made clear that the bonus Sasaki receives to sign will not be the determining factor. The most any team could theoretically offer is just more than $7.5 million that eight teams (the A’s, Brewers, Mariners, Marlins, Rays, Reds, Tigers, Twins) have in their '25 pools. "
