Rogers in final) and n the Tournament of Champions in Sofia (d. Muguruza in the semifinals and Pennetta in the final).At Roland Garros she sought revenge over Sara Errani and got into her first Grand Slam semifinal losing to the world No.4 Simona Halep, missing break and game points in the second set.
In 2015 she won her WTA title at Antwerp (won when Suárez Navarro withdrew prior to final w/neck injury) and lost two semifinals in Miami (l. to Suárez Navarro) and Charleston (l. to Kerber). After mixed results across the season, Petkovic ended the year at No.24, qualifying for the WTA Elite Trophy in Zhuhai (fell in group stage).
2016 season highlights included the semifinal run in Doha where she defeated Muguruza claiming her first win over a Top 5 opponent since d. No.2 Azarenka at 2013 Beijing (ret. against Ostapenko) and three quarter-finals appearances in Luxembourg, Dubai and Brisbane. She suffered first round losses at 2016 Rio Olympics in both singles (l. Svitolina) and doubles (w/Kerber, l. Errani/Vinci).
