<p>Novak Djokovic knows it isn't model behaviour when he loses his cool on the tennis court.</p>.<p>Yet he just can't help himself.</p>.<p>Exactly two weeks after he was defaulted from the US Open, and a day after he was warned by the chair umpire for breaking his racket in a fit of rage, Djokovic received an obscenity warning midway through a 7-5 6-3 win over Casper Ruud in the Italian Open semifinals Sunday.</p>.<p>The obscenity came in the third game of the second set, by which time Djokovic had a running dialogue with the chair umpire over a series of contested calls.</p>.<p>"I deserved the warning," Djokovic said.</p>.<p>"I didn't say nice things in my language.</p>.<p>"I had a couple of disputes with the chair umpire with those calls," Djokovic added.</p>.<p>"As I understood, I was three out of three right, but doesn't matter. Everybody makes mistakes. It's fine. It was a kind of the heat of the battle. There is a lot of intensity on the court. A lot of pressure for him, for both players. It's kind of whatever happens, happens."</p>.<p>As opposed to his previous two outbursts, this time there were fans in the stands who could clearly hear how Djokovic dealt with his frustration.</p>.<p>With 1,000 spectators allowed in to the Foro Italico for the first time this week, a large proportion of those in attendance were children.</p>.<p>"I don't want to do it, but when it comes, it happens," Djokovic said Saturday.</p>.<p>"That's how I, I guess, release sometimes my anger. And it's definitely not the best message out there, especially for the young tennis players looking at me. I don't encourage that — definitely."</p>.<p>Ruud was Nick Kyrgios' opponent during last year's Italian Open when the Australian walked off the court and threw a chair onto the red clay, leading to him being defaulted and fined.</p>.<p>"Some players, or especially Djokovic, (are) very passionate," Ruud said.</p>.<p>"Some players just by nature can show more emotions than other ones. That's part of the game."</p>.<p>Djokovic's behavior once again overshadowed his performance, in a match where he had to save two set points when Ruud served for the first set at 5-4 — one of them with a delicate backhand drop-shot winner.</p>.<p>The top-ranked Djokovic also served five aces in a single game to take a 6-5 lead in the first.</p>.<p>Ruud, 21, the first Norwegian player to contest a Masters 1000 semifinal and a product of Rafael Nadal's academy, put up plenty of resistance and also produced the shot of the day: a leaping over-the-shoulder hook shot for a winner as he raced back to chase down a lob — earning a thumbs-up from Djokovic.</p>.<p>"He has that pattern of play on clay with a lot of spin," Djokovic said.</p>.<p>"I'm sure we will see more of him in the big tournaments, especially on this surface. He's got the game."</p>.<p>Djokovic improved to 30-1 this year. His only loss came when he was thrown out of the US Open for unintentionally hitting a line judge in the throat with a ball during his fourth-round match against Pablo Carreño Busta.</p>.<p>In Djokovic's 10th Rome final on Monday — he has won four — he'll face eighth-seeded Diego Schwartzman, who edged 12th-seeded Denis Shapovalov 6-4 5-7 7-6 (4) in a match that lasted 3 hours, 15 minutes.</p>.<p>Schwartzman, who will play his first Masters 1000 final, beat nine-time Rome champion Nadal late Friday in the quarterfinals.</p>.<p>If Schwartzman also beats Djokovic — he's lost in all four of their previous meetings — he'll enter the top 10 of the rankings for the first time.</p>.<p>"That was in my mind all the match," Schwartzman said. "I was fighting."</p>.<p>In the women's final, top-seeded Simona Halep will face second-seeded Karolína Plíšková, the defending champion.</p>.<p>Halep reached her third Rome final by beating Garbiñe Muguruza 6-3 4-6 6-4 to improve her record in tennis' restart to 9-0. Plíšková defeated fellow Czech and last year's French Open finalist Markéta Vondroušová 6-2 6-4.</p>.<p>Muguruza struggled with her serve and double faulted on the final two points of the 2 hour, 16-minute match.</p>.<p>Halep lost to Elina Svitolina in the 2017 and 2018 finals.</p>.<p>"I'm not playing (Svitolina), so I have a plus," Halep said.</p>.<p>"I have just to manage it a little bit better than previous years. ... Now I'm more mature. So let's hope that I can be better tomorrow and to win it."</p>.<p>The second-ranked Halep is 13-0 overall stretching back to February, when she won a title in Dubai.
