June 12 (Reuters) - Scotland have picked 10 uncapped players in a 37-man squad for four tests in the Americas next month, coach Gregor Townsend said on Wednesday.

Forwards Gregor Brown, Nathan McBeth and Max Williamson are drawn from Glasgow Warriors, who play in the United Rugby Championship semi-final against holders Munster on Saturday, while winger Arron Reed was in the Six Nations squad this year.

His Sale team mate Gus Warr earned a first call-up, along with former Scotland Under-20 captain Robbie Smith, lock Ewan Johnson and Edinburgh's Matt Currie and Patrick Harrison.

Adam Hastings and Josh Bayliss returned after injury layoffs and hooker Dylan Richardson is also recalled.

Scotland start their month-long tour in Ottawa against Canada on July 6, before taking on the U.S in Washington D.C.

They face Chile in Santiago on July 20 and Uruguay in Montevideo on July 27.
