Rafael Nadal closed in on an eighth Rome Masters title as he dismissed old rival Novak Djokovic 7-6, 6-3 on Saturday to reach the final for a record-extending 10th time.
The last-four success will give the Spanish top seed added confidence ahead of the French Open, where he has won a record 10 titles.
Nadal, still unbeaten in semi-finals at the Foro Italico, unleashed a trademark clay-court attack after winning a tight first set lasting well over an hour.
"I need to be able to play my best tomorrow," Nadal said of a Sunday final against either defending champion Alexander Zverev or Croatian Marin Cilic.
"I'm very happy with my game. It all worked for me, the tactics, the shots."
The 31-year-old world No 2 cut the deficit in his head-to-head series with Djokovic to 26-25, after their 51st meeting since first facing off in 2006.
But the Serb complained afterwards about poor scheduling which affected his preparation, playing a late-afternoon quarter-final on Friday before returning to court on Saturday mid-afternoon.
"I don't want to seem like I'm complaining about losing the match because of the schedule. But having to end at night and coming back to play early in the day affects a lot," he said.
"Nobody has ever, ever reached me in my entire career to ask me about what I think would be the best scheduling. I don't think that is fair, we will address it in the next players' council."
Djokovic has rediscovered his form this week after months of elbow injury problems, including an operation earlier this year.
He can also feel his confidence increasing.
“I don’t think there was that much of a difference, which is great news for me. Winning the tie-break was for him a great wind in his back,” said Djokovic.
“Rafa was just better in the important moments, played the better shots. He deserved to win.
“I haven’t had many breaks in the last period, so I’m pleased by how I’ve played in the last days. I hope Roland Garros can be the continuation.”

Djokovic has rediscovered his form this week after months of elbow injury problems, including an operation earlier this year.
Nadal now stands 10-8 over Djokovic in semi-finals, with the pair having played each other at all four grand slam tournaments, the ATP Finals, Davis Cup, the Olympic Games along with eight of the nine Masters 1000 events.
Djokovic, one of only two men ever to beat Nadal at Roland Garros, traded with his rival from the baseline and at times outplayed him, even if it was not quite enough in the end to topple him.
Nadal took 73 minutes to win the opening set after leading 5-2.
But to take the early lead, the top seed had to avoid being reeled in by Djokovic.
Djokovic, a four-time Rome winner and former world No 1, battled back to 5-5 with a break of the Spaniard before the set went to a tie-break, which Nadal took on the first of two set points with a backhand winner down the line.
Nadal took a 2-1 lead in the second set with another break of Djokovic and never lost control.
The top seed kept his nose ahead until the end, winning on his second match point as he fired another untouchable backhand.
Nadal will regain the world No 1 ranking from another long-time rival Roger Federer should he win Sunday's final, while Djokovic can head to the French Open in Paris, which gets under way next week, knowing he is a contender for the biggest titles once more.
