Chasetown FC suffered their third defeat in as many games as they went down 2-1 at home to Lincoln United.
Thomas went closer to breaking the deadlock just before half-time with a fierce close range effort that Turner beat away for a corner.
The visitors hardly threatened the Chasetown goal in the first half but took the lead eight minutes after the break with Conner Robinson drilling a shot beyond returning keeper Ryan Price.
Chasetown responded immediately and full back Liam Holt burst forward and exchanged a pass on the edge of the box before beating Turner at his near post.
Out of nothing the Scholars almost levelled with a Rhys Thompson curler that came back off the post.
Turner then tipped an effort from Thomas over the bar as the hosts pushed for an equaliser.
But Lincoln added a fortuitous third as Price fired a clearance straight at McGovern after a poor back pass to him and the ball trickled into an unguarded net.
