Middlesbrough fought back from an early own goal to snatch a win at Barnsley.
Barnsley, still looking for their first win of the campaign, were gifted a fifth-minute lead when Stephen McManus put into his own net.
But Scott McDonald headed home Barry Robson's corner in the 11th minute before the latter tapped home two minutes later.
Marvin Emnes, with his sixth goal in four games this season, completed the scoring on the stroke of half-time.
Barnsley's first goal of the season came from an unexpected source when David Perkins' cross was stabbed into his own net by McManus under pressure.
The visitors responded almost immediately, McDonald rising unmarked to glance home Robson's inswinging corner.
McDonald then tore apart the home defence and found Robson who clipped the ball home to put the visitors ahead with 13 minutes on the clock.
Barnsley striker Danny Haynes beat the offside trap as the home side looked to get back on level terms, but his weak effort was kept out by Carl Ikeme.
Robson was close to doubling his tally moments later but his curling free-kick drifted just wide.
Emnes then added a third for Middlesbrough two minutes before the break when he latched on to McDonald's pass and steered the ball under Luke Steele.
Julio Arca and McDonald were denied by Steele as Boro continued to press after the restart, before Emnes wasted the best chance of the second half when he failed to steal the ball from Steele's feet in a moment of confusion.
