Match ends, The New Saints 0, Videoton 1.
The New Saints face an uphill task in their Champions League second qualifying round tie with Videoton after losing the first leg at home.
The Welsh side were holding their own at Park Hall against their Hungarian visitors until 13 minutes from time.
But Christian Seargeant was caught in possession and Adam Gyurcso struck a low shot into the far corner past Paul Harrison in the TNS goal.
The second leg is on 22 July at the Sostoi Stadion in Szekesfehervar.
Aeron Edwards had a late chance to equalise but his snap-shot from just outside the area was touched over the bar by alert Videoton keeper Peter Gabor.
TNS manager Craig Harrison said: "We did reasonably well, we were organised, we defended well, we were very dangerous on the counter-attack.
"We've had opportunities and unfortunately on 77th minute to give a goal away is disappointing.
"But the players are still positive because there's no reason we can't go out there and score in Hungary."
