Scotland lose despite spirited comeback
Second placed Scotland had to try and come back from 3-0 down after 63 minutes against Greece, having gone into half time a goal down after Anastasios Bakasetas seventh minute opener.
Ben Doak pulled one back in the 65th minute for his first international goal before Ryan Christie reduced the deficit to one goal after scoring his header from Andy Robertson's cross.
Greece captain and opening goalscorer Bakasetas was sent off after receiving a second yellow card as the Scots pushed for an equalizer.
Greek goalkeeper Odysseas Vlachodimos produced two big saves late in the match as he kept out Scott McTominay's attempt with his leg before denying George Hirst a tap in from six yards out to help his side claim the win.
