(CBS) The White Sox have signed nine of their top 10 picks from last week’s MLB amateur draft, they announced Wednesday afternoon, including second-round pick Spencer Adams, an 18-year-old right-hander from White County High in Cleveland, Ga.

Of Chicago’s top 10 picks, only first-rounder Carlos Rodon remains unsigned. A left-hander out of North Carolina State who’s believed to be the most major league-ready pitcher in the draft, Rodon is represented by powerful agent Scott Boras, so negotiations may take some time, as 670 The Score beat writer Bruce Levine detailed here.

In addition to Adams, the other early round draftees the White Sox signed were left-hander Jace Fry (Oregon State), catcher Brett Austin (North Carolina State), right-hander Zach Thompson (Texas-Arlington), outfielder Louie Lechich (San Diego), shortstop Jake Peter (Creighton), shortstop John Ziznewski (Long Island University-Brooklyn), left-hander Brian Clark (Kent State) and second baseman Jake Jarvis (Klein Collins High in Cypress, Texas).

Terms of the signing bonuses for the new White Sox weren’t disclosed, but most presumably signed for their slot value. If you’re interested in what each slot value was, Baseball America has the breakdown here.

In all, the White Sox have signed 28 players who they drafted, they announced.
