On Monday, the Detroit Tigers used the fifth-overall pick and selected high school outfielder Riley Greene.

On Wednesday, less than 48 hours after drafting him, the Tigers announced that they've already signed Greene to a rookie deal.

According to MLB.com's Jim Callis, Greene agreed to the full slot value for the fifth overall pick, which is just under $6.2 million.

That's seems pretty quick, right? I mean, the draft is still going on. As we know, teams can't talk to players about a contract before the draft, because that would be improper and illegal. I guess you can chalk it up as the two sides working really hard to get this thing done as soon as possible.

Anyways, the Florida high school outfielder will be introduced to the media at Comerica Park on Friday to make it official. Greene projects as one of the best hitters in this draft class, and with plenty of top arms already among their best prospects, Detroit's farm system is looking better by the day.
