A straight-sets win over 11th seed Stanislas Wawrinka on the opening day was more than many expected 32-year-old Hewitt was capable of after years of hip trouble threatened his career.
He appears to have saved his best form of the year for the short grass-court stretch having reached the semi-finals at Queen's two weeks ago and now sending home a player who was runner-up in the 's-Hertogenbosch final on Saturday.
Not that Hewitt is allowing himself to be carried away by any growing expectations, even if his quarter of the draw has become much more navigable with the exit of Rafael Nadal.
"I'll take it one match at a time," Hewitt said.
"The moment that you knock off a decent player, then let your guard down, that's when you're going to go out of the tournament.
"I still have to stay composed, be confident. I know that I'm hitting the ball well. I've still got to go out there and do the job, though.
"I know that I can still play the game. I compete against the best guys. I play well in the big tournaments, I think. That's why I'm still playing.
"It's obviously been a few years since I felt physically good on the court. It makes some of these wins even more special for me, to know what I've been through, to still be here."
On Wednesday the Adelaide man faces Dustin Brown, the 189th-ranked Germany-born Jamaican who saw off Spaniard Guillermo Garcia-Lopez in the first round.
Hewitt is in the dark about what to expect.
"I've never really seen him play. I've never hit with him. Never really seen a lot of him," Hewitt said.
"I'll have to be on my game."
Eleven years have elapsed since Hewitt beat David Nalbandian to win his Wimbledon title and his second grand slam, having triumphed at the US Open 10 months earlier.
He savours each return to the All England Club, having been ever-present since his debut in 1999.
"I embrace it. I've only got good memories from here really," Hewitt said.
"As a kid growing up, if someone was going to say you're going to win one Wimbledon, I would have taken it every day of the week, and that being the only tournament.
"For me, it's always a special place to come back to, and always will be."
