Two set-pieces did the trick for Middlesbrough as they saw off Portsmouth to mathematically secure their top-flight status.
Boro made a tentative start to the game but both teams created chances in what was turning out to be a fairly even contest at the Riverside.
However, slack defending cost the visitors five minutes before the break as an unmarked Chris Riggott rose to power Fabio Rochemback's corner past a helpless Jamie Ashdown.
The home side then grabbed the killer second eight minutes after the restart, this time Tuncay eluding his marker, Glen Johnson, to guide his near-post header from Stewart Downing's corner low into the corner.
Niko Kranjcar went closest for Pompey with a thunderous 30-yard free-kick and a curling effort from the edge of the box but they didn't work Mark Schwarzer nearly enough as Boro confirmed their Premier League survival.
