Ivanovic had reached the semi-finals at Wimbledon in 2007 and was heavy favourite to beat her world ranked 158 opponent.
Mattek-Sands will face Swiss teenager Belinda Bencic for a place in the Last 16. Ivanovic is the third top 10 seed to lose this week.
The women's draw opened up even further when Russian eighth seed Ekaterina Makarova, a quarter-finalist in 2014, went down 6-2, 7-5 to unseeded Magdalena Rybarikova. Before this tournament, the World No 65 Rybarikova had never won a match at Wimbledon in seven years of trying.
Wozniacki, Kerber through
Makarova joined third seed Simona Halep, seventh seed Ana Ivanovic and Carla Suarez Navarro, seeded nine, in failing to get beyond the second round.
Former World No 1 Caroline Wozniacki made the third round with a 6-1, 7-6 (8/6) win over Denisa Allertova, the World No 83. Wozniacki next takes on 31st seed Camila Giorgi.
German 10th seed Angelique Kerber was also a winner, seeing off Russia's Anastasia Pavlyuchenkova 7-5, 6-2 while 2012 runner-up Agnieszka Radwanska defeated Ajla Tomljanovic 6-0, 6-2.
