"A more recent addition to the negotiations is an NBA-style lottery system for the draft. The league believes it will at least partly address players' tanking concerns. Right now, the team with the worst record in baseball gets the No. 1 pick in the amateur draft the following summer. It's created a "race to the bottom," as agent Scott Boras put it earlier this month.
The league is offering a system where all non-playoff teams would have a chance at the No. 1 pick -- not just the team with the worst record. The worst team would still have better odds than the second-worst team, and so on and so forth, but in theory, any non-playoff team could end up with a top-three pick.
The lottery would only be for picks No. 1 through No. 3, then the draft would continue as it has in the past, based on regular-season record. The playoff teams would pick according to how they finished in the postseason. The World Series winner would pick last."
I don't see the point of a lottery system in the MLB draft in it's current format with draft slot values and draft pools and the ability to spend more than a slot value. The top talents still have relatively decent chances of not being taken #1.
