For 2020 we have a much shorter draft now - just 5 rounds.
Via: MLB Trade Rumors
This will be a big impact on teams. The Jays get the 5th overall pick and the 5th pick in each round after that. So picks #5, 42, 77, 107, 137 and that is it (via MLB). Normally having such a high draft pick means you get many rounds of advantage but instead just 5 of them. Then everyone else is a free agent with a $20k cap on bonuses. Ouch. I suspect many players will wait a year rather than sign in that case with a massive draft class the next 1-4 years as high schoolers go to college for 2-4 years instead of signing.
