James Anderson and England endured a frustrating afternoon as DRS came to the rescue of Australia pair Shaun Marsh and Tim Paine on day two of the second Ashes Test.
Anderson (1-64) thought he had dismissed Marsh and Paine lbw before tea at Adelaide Oval - the umpire raising his finger on both occasions Sunday.
But on both occasions, Marsh (49 not out) and Paine reviewed, and they were successful in silencing the English - the latter going on to bring up his third Test fifty.
Paine's impressive innings came to an end on 57 when he pulled a Craig Overton delivery to Moeen Ali at deep square leg as Australia reached 306-6 at tea of the historic day-night match.
England made a stream start, paceman Stuart Broad (1-51) charging in and making the early breakthrough by trapping Peter Handscomb (36) lbw with the third delivery on Sunday - Australia resuming at 209-4.
Anderson - vocal leading into the Adelaide match after accusing Australia of bullying - was taken out of the attack momentarily by captain Joe Root, having struggled for pace and length but the veteran returned and celebrated two wickets before DRS took over.
A fuller delivery to Marsh - forward from his crease - came back and hit the Australian on the knee roll, and it was given out, however Anderson's celebrations were short-lived after hawk-eye showed the ball bouncing over the stumps.
With the movement of the pink ball causing all kinds of problems, it was a similar story for Anderson in his next over when the umpire's finger went up again after Paine was hit in front of the wickets but height was an issue once more as the wicketkeeper successfully reviewed.
