They had brief respite with the wicket of Labuschagne, who fell short of a second double ton amid his purple patch of three straight centuries. The No.1 ranked Test batter also passed 3000 Test runs in just his 51st innings with only Don Bradman reaching the landmark faster for an Australian batter.

Hometown hero Head, however, passed his highest score of 161 to continue dominating a lackluster West Indies attack much to the delight of the Adelaide Oval faithful. West Indies once again rued sloppy bowling, while skipper Kraigg Brathwaite’s tactics were rather puzzling underlined by often not implementing a gully in a conservative move.

He was generally reactionary, but a second-string attack hasn’t helped his cause. A shorthanded West Indies attack, without spearheads Kemar Roach and Jayden Seales, was further depleted with debutant quick Marquina Mindley likely out for the match after suffering a hamstring injury early on day one after bowling just two overs.

Medley had arrived in Adelaide from the Caribbean just 48 hours before the Test as injury cover. Amid their increasing woes, West Indies desperately needed a spark on day two and speedster Alzarri Joseph belatedly tried to provide one with several menacing short deliveries to test Labuschagne reminiscent of his fiery spell on day four in Perth. With the surface appearing quicker than on day one, marked by tennis ball-like bounce, Joseph frustratingly couldn’t penetrate for long enough with debutant Devon Thomas showing up the frontline bowlers.

Having taken the wicket of opener Usman Khawaja on day one, Thomas’ handy seamers again did the trick and he removed Labuschagne and then almost dismissed Cameron Green, who edged his first ball of the series in front of the slips. It was a brief bright spot for West Indies after being plundered by Labuschagne and Head, who notched their 200-run partnership on the second ball of the day’s play.

Head had capitalized on overpitched West Indies bowling en route to a rollicking first hundred in front of the home faithful. He encountered more accurate bowling early on day two and was fortunate that a rare edge sailed through the slips to the boundary. Normal service resumed with Head flamboyantly slashing over gully for consecutive boundaries as he overtook Labuschagne to reach 150 with a boundary off the innocuous spin of Roston Chase.

Labuschagne also reached the landmark before his surprise wicket, as a focused Head batted cautiously through to the break knowing he has a golden opportunity at his fingertips.
