document: Baker, 23, and Thornton, 20, trained with Wales ahead of the 2015 World Cup, but were omitted from the squad.
  Both have signed three-year deals, taking the total of players on NDCs to 16, with Ospreys contributing half.
  Their salaries funded 60% by the Welsh Rugby Union and 40% by the regions.
  Baker has been capped three times and Thornton led Wales Under-20 in the 2015 Six Nations.
  The duo's deals were announced a day after Ospreys hooker Scott Baldwin and back-five player James King signed dual contracts.
  Baldwin, 27, was his country's first-choice hooker at the recent World Cup and has signed until 2019.
  Lock or back-rower King, 25, has secured a deal until 2018.
  The deals, which give the Welsh Rugby Union more control over players, were introduced to help stem the exodus of stars such as Toulon's Leigh Halfpenny from Wales.
  Newport Gwent Dragons number eight Taulupe Faletau turned down a dual contract in May 2015 and Bath's recent bid to sign him was vetoed by Wales coach Warren Gatland.
  Baker, Thornton, Baldwin and King have signed against a backdrop in which fly-half Rhys Priestland has taken an 18-month Test rugby sabbatical to concentrate on playing for Bath after leaving Scarlets.
  Gatland said: "Dan and Rory are players of significant potential.
  "We look forward to continuing to work with them at national squad headquarters, but also to watching them continue to flourish for the Ospreys."
  Fly-half Biggar is expected to sign a contract extension, but lock Jones is considering his future beyond the end of the 2015-16 season.
  Wales captain Sam Warburton was the first of the nation's current generation to commit to a dual deal.
summary: Ospreys number eight Dan Baker and uncapped lock Rory Thornton have become the latest Welsh players to sign national dual contracts (NDC).
