The victory at Karen Rolton Oval completed a wonderful week for South Australia after they earlier completed their first Sheffield Shield win over the Victoria in nine years.

Harvey's unbeaten 134 off 110 balls, his first in the format, was complemented by skipper Alex Carey initially in an 80-run opening stand before Drew (108 not out off 86) made an equally impressive ton to chase down Victoria's 286 for 7 in the 38th over to claim a vital bonus point.

Harvey, 24, gave the run chase a real kick along when he took 16 off Sam Elliott's first over. It was a masterclass by the stylish left-hander who grafted for his runs early before accelerating and dominating his former team to earn player-of-the-match honours.

Harvey, the nephew of former Australia allrounder Ian Harvey, easily surpassed his previous highest domestic one-day score of 61.

Drew, 28, was just as impressive and lifted the tempo to ensure his team claimed the win inside 40 overs to get what could be a crucial extra competition point.

Earlier, Johnson took 4 for 46 in a fast and furious spell that set up the win after Carey had won the toss. Johnson removed big-hitting Josh Brown when his former Brisbane Heat teammate was brilliantly caught by a diving Drew at mid-off.

His second wicket was a tribute to the left-armer's searing pace and attacking mindset. Johnson let rip with a straight short ball that had Campbell Kellaway rushing his pull shot and gloving through to Carey.

Handscomb came in with Victoria reeling at 42 for 3 and showed aggression and patience depending on what was required. After lashing a suite of boundaries and two imperious sixes, Handscomb accumulated 15 singles in a row.
