Scotland's run of friendly defeats at Hampden stretched to seven after a lacklustre display against Hungary.
Szabolcs Huszti scored from the penalty spot on the stroke of half time and the same player blasted in a stunning long-range shot in the 53rd minute.
The visitors were gifted another goal when Steven Pressley cannoned a clearance off keeper David Marshall and into the Scotland net.
The Scots lacked attacking ideas and rarely threatened the Hungary defence.
Celtic goalkeeper David Marshall won his first international cap and the teenager had little to do in the opening stages as the visitors sat back.
Nigel Quashie, Barry Ferguson and Darren Fletcher showed some nice early touches in midfield but there was a lack of positive thrust about the Scots.
Strikers James McFadden and Kenny Miller were starved of good service and all too often had to come deep or drift wide to receive the ball.
Quashie tested Hungarian keeper Gabor Kiraly with a powerful low shot after eight minutes and, soon after, the new Crystal Palace signing had to hold on to a snap-shot from Andy Webster.
There was a let off for Scotland when Kovacs drifted in behind the Scottish defence but the striker failed to connect with his attempted header.
Seven minutes before the break Quashie danced past a couple of challenges on the edge of the Hungarian penalty box but the Portsmouth man's shot flew over the crossbar.
In the 43rd minute Scotland had a penalty appeal turned down when Fletcher was tugged and tripped by an opponent.
And deep into first-half injury time the visitors were awarded a soft spot-kick when Kovacs lost his footing following a clumsy challenge from Webster.
Huszti stepped up and slammed the ball home, with Marshall diving the wrong way.
Szabolcs Huszti scores from the penalty spot
Seven minutes into the second half Huszti raced from the halfway line with purpose and let fly with a stunning shot from 25 yards that whistled past the diving Marshall and into the net via the post.
McFadden squandered a good opportunity when he wanted too much time just eight yards out and was eventually crowded out.
Kovacs then came close for the visitors when his looping header drifted narrowly wide.
And Zoltan Gera tried his luck with a flamboyant hooked shot that Marshall pushed over brilliantly.
Marshall's vexing introduction to international football took a turn for the worse when Pressley slid in to cut out a cross from Peter Simek and the ball hit the prone keeper's back and rolled into his net.
Substitute Stevie Crawford was given a glimpse of goal in the 82 minute but the Plymouth striker lashed the ball over from 12 yards.
Scotland have just one warm-up match - a tough test in Spain - before World Cup qualifying begins against Slovenia on 8 Septemeber and the signs are all rather depressing.
