(CNN) -- World No. 1 Dinara Safina marched into the final of the Cincinnati Open after comprehensively ending the 15-match winning streak of Flavia Pennetta on Saturday.
Dinara Safina needed less than an hour to brush aside Flavia Pennetta in the Cincinnati semifinals.
The Russian crushed the in-form 14th seed 6-2 6-0 in just 56 minutes to set up a showdown with fifth seed Jelena Jankovic.
Safina, who ended the comeback of former world No. 1 Kim Clijsters in Friday's quarterfinals, reached her eighth final in 14 tournaments this year.
She was far too strong in the semifinal for Pennetta, who will be the first Italian to be ranked in the top-10 when the WTA Tour releases its latest list on Monday.
The 23-year-old was in control after winning the first two matches, and now has a 7-0 career record over Pennetta.
"Every match I feel better," Safina told reporters. "Today, stepping on the court, I was feeling very good and confident. I was feeling very good stepping in."
Pennetta was playing her 11th match in 13 days, having knocked out third seed Venus Williams in the third round of the hardcourt tournament following her title in Los Angeles.
"She was playing much better than me," the 27-year-old said. "I was a little bit tired, of course, but I didn't lose for that. She was playing unbelievable."
Meanwhile, Jankovic won an epic semifinal against fourth-seeded Russian Elena Dementieva on Saturday night.
The Serb prevailed 7-6 0-6 7-6 in a match lasting two hours and 46 minutes and will now go in search of her second title of 2009 after her only previous success came in Marbella in April.
Jankovic squandered three match points in the third set as Dementieva forced the tie-breaker. She then fell 6-2 behind before winning the final six points to claim an unlikely victory.
"I don't believe I won this match," Jankovic told reporters afterwards.
