Maria Sharapova said Tuesday that her third-round China Open clash with world No 2 Simona Halep will help the Russian gauge her progress since returning from a 15-month doping ban.
The former world No 1, on the comeback trail since April following the ban for taking the banned substance meldonium, had to dig deep as she defeated compatriot Ekaterina Makarova over three sets in the second round.
Sharapova, a lowly 104 in the world and on a wild card at the China Open, has yet to win a tournament since returning to tennis.
The five-time grand slam champion said she had endured "a few ups and downs" in seeing off Makarova 6-4, 4-6, 6-1.
But the 30-year-old Russian is relishing her showdown with the Romanian Halep: "We know each other's games very well, that's no secret.

"They've always been very challenging, tough, competitive, emotional."
Sharapova, a crowd favourite in Beijing, added: "But I love the challenge of playing against someone that's No 2 in the world.
"She's a great player; she's had a great year.
"Any time you're able to face an opponent that's done something right and well, it's great to see where you are and where your level is."

The Halep meeting will be a replay of the first-round match between the pair at the US Open in August, when Sharapova made an impressive return to grand slam competition before exiting in the fourth round.
Sharapova holds a 7-0 record against Halep, who made it into the next round on the outside Beijing hard courts after Magdalena Rybarikova retired ill in the second set.
Tuesday's encounter with Makarova was the second time in four days that Sharapova had been forced into a deciding set.
And the Russian believes tournaments such as the China Open are only getting harder to win.

"There's a lot of depth in the game, by that I mean there's maybe many years ago you'd find yourself working through the first rounds," she said.
"You knew you're going to get through those first few rounds, it will be straight sets -- you might be rusty, but you'll get through it.
"You can't think like that any more, there's too many good players playing the first, second, third, fourth rounds."
