Hello
Perth replaced Adelaide Oval as Cricket Australia's preferred choice for the season opener.
Defending a victory target of 450, Australia's much-vaunted seam attack destroyed Pakistan's top-order in the afternoon, allowing Lyon to trap tail-ender Faheem Ashraf lbw and celebrate his milestone before the tourists folded up inside 31 overs.
Off-spinner Lyon sits on 499 Test wickets after claiming 3/66 while Imam-ul-Haq top-scored with 62 for the visitors, who were bowled out in 101.5 overs.
Pakistan batted for 53 overs in the afternoon to reach 132/2 at stumps as the visitors trail by 355 runs.
The future of the Games more broadly remains up in the air, with Canada's Alberta province also withdrawing its support for a bid for the 2030 event.
The Proteas were home and dry with two balls to spare in their chase of 134.
Perth is scheduled to host the fifth and final Test from January 14, but Sports Minister Colbeck said the Western Australia capital might have to miss out because of the state's quarantine requirements.
The ATP Cup will have 750 ranking points and $22 million in prize money up for grabs. The event leaves no room in the revamped tennis calendar for the Hopman Cup, which is popular with players and served as a warm-up for the Australian Open.
India, who won the opener at Adelaide Oval by 31 runs, have never won a Test series in Australia.
Mohammed Shami picked up a career-best 6/56.
