In June 2013, Meusburger entered the qualifying tournament of the Wimbledon Championships, defeating Nicole Gibbs, Tamarine Tanasugarn, and Sesil Karatantcheva for a spot in the main draw.

The following month, she advanced to the final of the Budapest Grand Prix, beating three seeded players en route.

Meusburger consequently re-entered the top 100 and overtook Tamira Paszek to become Austria's top-ranked women's player.

This win, along with a successful end to the 2013 season, meant that, at the age of 30, Meusburger's ranking moved into the world's top 50 for the first time in her career.

Ranked 49 in the world, Meusburger reached the third round of a Grand Slam tournament for the first time in her career at the 2014 Australian Open.

Meusburger returned to defend her title at the 2014 Gastein Ladies and started off well when she defeated qualifier Tereza Smitková in a match lasting nearly three hours.

Meusburger played her last professional match at the 2014 US Open, announcing her retirement following a first-round loss to Karolína Plíšková of the Czech Republic.
