Kerber beats Ivanovic to win Linz title
The 10th-ranked German used three breaks to win the opening set and saved four set points for Ivanovic in the second.
Kerber reached her third final of the year. She lost to Petra Kvitova of Czech Republic in Tokyo two weeks ago.
Kerber didn't intend to play in Linz but was given a late wild-card entry to replace Kvitova after the former Wimbledon champion pulled out with a back injury.
The former top-ranked Ivanovic, who won the event in 2008 and `10, appeared in her first final since winning her 11th career title in November 2011 in Bali, Indonesia.
