Despite losing the pair’s only previous meeting at the 2013 US Open the German ruthlessly set about dispatching her opponent, breaking on six occasions for an easy 6-2 6-0 victory.
''Apart from the first set of my first match, everything is going very well this week,'' said Kerber, who was referring to her first round match against Monica Niculescu in which she lost the opening set to love.
"I feel better with every round. Today I was more aggressive than in my previous matches."
Ivanovic endured a slightly trickier encounter against Switzerland’s Stefanie Voegele – who shocked American Sloane Stephens on Friday – but emerged victorious 6-4 6-4 to earn her first final spot of the season.
The Serb created numerous openings on Voegele’s serve and now has her sights set on claiming back the title she previously won in 2008 and 2010.
"It wasn’t an easy draw for me so I am happy to get though," said Ivanovic. ''I am still looking for more consistency.''
