For the first time in draft history, teams have exchanged picks.

As part of the deal that will send Anibal Sanchez and Omar Infante to the Tigers and Jacob Turner and a pair of prospects (catcher Rob Brantly, lefthander Brian Flynn) to the Marlins, the clubs swapped the picks they won in the competitive-balance lottery last Wednesday.

Designed to give small-market teams and revenue-sharing recipients additional draft picks (and thus extra bonus pool money for the first 10 rounds), the competitive-balance lottery selections are the only choices that may be traded. The Marlins gave up the last pick in the supplemental first round (currently No. 37) for the final pick in the supplemental second round (currently No. 73).

This year, the No. 37 selection had an assigned value of $1,394,300 and the No. 73 choice was worth $701,700. That's a difference of $692,600. Those values will be adjusted based on the growth of industry revenues this year, so how much exactly the Tigers added to their bonus pool and the Marlins subtracted from theirs has yet to be determined.

Competitive-balance lottery picks can't be traded more than once, so these two selections won't change hands again. The lottery choices can only be traded during a regular season, up to two hours before the draft.
