Williams, who turns 40 this year, has been stuck on 23 since winning the 2017 Australian Open, losing four finals since to remain one short of Margaret Court’s record.
But Evert believes Williams, despite worries over a shoulder niggle, will be a big threat in Melbourne.
“She’s looked awfully good. If anything, she’s looked probably better than anybody else to me,” ESPN expert Evert, twice an Australian Open champion, said ahead of the tournament which starts on Monday.
“Even though you don’t consider her an underdog, she still is as far as rankings are concerned. She’s the type of player that could come and win this tournament for sure because the other top players aren’t match tough, in my mind.
“Serena doesn’t need tournaments necessarily as she’s proven in the past 20 years to play her best tennis.”
The tournament is taking place three weeks later than normal and players have had their usual preparations restricted by COVID-19 quarantine protocols.
“She (Williams) looks quicker than I saw her last year when she was playing, even the year before when she was playing,” said Evert who won 18 Grand Slam singles titles.
“She looks like she’s really improved her movement. Her fitness looks good. She’s striking the ball well.”
“I’ve watched Naomi (Osaka). I’ve watched (Sofia) Kenin. I’ve watched most of these players. Simona (Halep). Nobody is in top form yet. I mean, for Serena to sneak in there and take this title wouldn’t surprise me whatsoever.”
