The third Ashes test has again been marred by controversy with English opening batsman Mark Stoneman falling victim to a dubious DRS decision on the first day of the clash in Perth.
With the visitors on 131-4, Stoneman was given out by third umpire Aleem Dar - caught behind for 56 - after gloving a ferocious Mitchell Starc bouncer.
Stoneman was originally given not out by on-field umpire Marais Erasmus, but Australian skipper Steve Smith immediately reviewed the decision after a decent grab by wicketkeeper Tim Paine.
TV replays showed the left-hander fending in front his face, with his bottom hand slipping off the bat handle.
