For any player returning from such a long absence, it takes time to find match accuracy and it will take patience in order to progress.
With Raducano, given the long list of physical and mental struggles she has endured since winning the 2021 US Open, extra caution is necessary.
So it was not surprising – but not necessarily alarming – to see Raducano struggle physically in the deciding set of the intense battle with 94th-ranked Wang.
The way she pulled through the three-hour competition, showing glimpses of her undoubted quality, was encouraging and impressive.
In the breeze of a test, Wang played with precision and intelligence in the first set as Raducano paid the price for a slow start.
The former British number one was unable to recover from two breaks and dropped serve again in the first game of the second set.
When Raducano faced two more break points at 1-1, it looked as if Wang's toughness would be enough to win in straight sets.
But there was much to admire about Raducano's response.
She managed to raise her game, putting an extra spring in her step, and immediately broke to level the score at 2-2 on the fifth attempt.
When Wang again served into the wind at 4-3 down, Raducanu stuck to another baseline duel and ended a 24-shot rally with a cross-court forehand to take the lead into the break.
Getting over the line was difficult. But competing on the biggest stages of all is where Raducanu wants to be and she has shown her resilience.
Raducano wasted two service points, but took advantage of a fourth chance in the next game to force a deciding decision.
The two players took a break before the start of the third set and gave Raducano the early advantage by missing a forehand that she expected to miss.
Then came the difficulty breathing and feeling nauseous. When I fell 2-0 down, I asked for a doctor's evaluation and he prescribed some pills.
However, Raducano refused to give up. The Briton had four more break points before Wang served to reach the third round at a Grand Slam for the first time.
