Now that Major League Baseball has gone through its first Draft and signing period under the new rules of the Collective Bargaining Agreement, it's time to move on to the next phase of the new system: the Competitive Balance Lottery.

The lottery, scheduled to take place Wednesday at 1:30 p.m. ET in New York, is a mechanism designed to help teams perceived to need the most assistance by awarding extra Draft picks to some of them. The 10 smallest-market teams and 10 lowest-revenue teams will have the chance to win one of six extra selections in the 2013 First-Year Player Draft.

Those half-dozen picks will be made at the conclusion of the first round, following the compensation selections. Because there is obvious crossover between those two groups, there are 13 teams entered into the first-round lottery: the D-backs, Orioles, Indians, Royals, A's, Pirates, Padres, Rays, Reds, Rockies, Marlins, Brewers and Cardinals. The odds of winning a Draft pick will be based on each team's winning percentage in the previous season.
