Watson's big-score formula is to free the mind, take game on!

Shane Watson knows he is a tease, but the star Australian all-rounder hopes he has finally found the key to unlocking his potential, according to reports.

According to the Sydney Morning Herald, Watson's brilliant century in the third Test in Perth highlighted what a special talent he is but it only came about after the 32-year-old employed a free-wheeling mindset in a bid to get out of his form slump.

Watson said that from ball one in the second innings, he just went out there making sure he was taking on the game, adding that it is when he is batting at his best.

He added that it is more so just trying to have the same mentality, having that intent and taking on the bowlers.

Watson also snared two key wickets from 23 overs in Perth to help lift Australia to an unassailable 3-0 lead in the series heading into the Boxing Day Test, the report said.

The 49-Test veteran described the Ashes triumph as the most special experience of his career, the report added.
