Queens Park Rangers are currently leading Swansea City 1-0 after the opening half at Loftus Road.
In a 45 minutes of few chances, the hosts had an early opportunity when Akos Buzsaky lashed his shot narrowly wide of Michel Vorm's post.
Vorm was called into action soon after, but he made a comfortable save from Jamie Mackie after he had been teed up by strike partner Bobby Zamora.
Joey Barton, who was being booed by some sections of the home support, tried his luck from distance with 30 minutes gone, but the captain's drive flew high over the crossbar.
However, the midfielder did better in first-half injury time as his low shot in a crowded penalty area found the bottom corner.
