Fifth seed and 2012 champion Bojana Jovanovski was a come-from-behind opening-round winner Monday at the Baku Cup tennis event.
The Serb overcame Austrian Patricia Mayr-Achleitner, 2-6, 7-5, 6-3, on the hardcourts at Baku Tennis Academy.
A Day 1 upset came when Israeli veteran Shahar Peer took out sixth-seeded Austrian Yvonne Meusburger, 6-2, 6-4. Peer was last year's Baku runner-up to Ukrainian Elina Svitolina, who is this week's second seed.
Poland's Urszula Radwanska was leading Alison Van Uytvanck 6-1 when the Belgian retired.
Additional wins came for Poland's Katarzyna Piter, Swiss Stefanie Voegele and France's Pauline Parmentier.
The top-four seeds will all take to the courts on Tuesday, including top seed Sorana Cirstea of Romania.
The 2014 Baku champ will claim $43,000.
