A rejuvenated Jordan Thompson has won just his fourth match at a major in 18 attempts, thumping veteran Spaniard Feliciano Lopez in straight sets on day one of the Australian Open.

The 24-year-old Sydneysider won 6-1 7-6 (9-7) 6-3 on Monday, setting up a second-round clash with either American Steve Johnson or Italian Andreas Seppi.

The world No.72 also reached the quarter-finals at last week’s Sydney International before bowing out to countryman Alex de Minaur.
