Steve Smith is in an ominous form and it is his 6th Ashes ton in his last 10 Ashes innings. Resuming on 124-3, Smith continued to put England to the sword, passing 100 post-lunch. England have not dismissed Smith with a red ball for a score under 50 since the second innings of the Trent Bridge test in 2015.
Australia captain Tim Paine said former skipper Smith had given batting coach Graeme Hick long and taxing work-outs in the nets as he looks to hone his formidable game ahead of the Ashes opener in Edgbaston on Aug. 1.
The push for the use of concussion substitutes gained momentum after the unfortunate death of Australian cricketer Phil Hughes, who was struck on the head by a ball during a Sheffield Shield match in November 2014.
