The Pole and the Slovenian on Sunday saw off the Czech Republic's Lucie Hradecká and India's Sania Mirza 6-2, 4-6, 10-7 in the championship match to claim their first title together.
The win marks the first Women's Tennis Association (WTA) doubles title for Poland's Linette, who has a world doubles ranking of No. 36.
