It hasn’t even been 24 hours since the draft started, and a first-rounder already has signed. Stanford righthander Drew Storen, the No. 10 overall pick, has agreed to terms with the Nationals for a $1.6 million bonus.

Washington received the No. 10 pick as compensation for not signing first-rounder Aaron Crow last year, but wouldn’t have gotten another choice had it failed to sign this one. It was no secret that the Nationals were going to take a player they’d be confident in signing. Storen had extra leverage as a draft-eligible sophomore, but he also went as high as he could have gone after projecting to go in the late first or sandwich rounds.

Last year’s No. 10 choice, Stanford catcher Jason Castro, signed with the Astros for MLB’s slot recommendation of $2.07 million. Commissioner Bud Selig has slashed slots by 10 percent this year.
