In 2016, Azarenka became the third player to win Indian Wells and Miami in the same year, following Stefanie Graf (1994, 1996) and Kim Clijsters (2005); Osaka begins her campaign to emulate that feat against Williams.
Azarenka is also a three-time Miami champion, with her first win coming in 2009. She followed that up with victories in 2011 and 2016.
Bellis and Azarenka have met only once before - last year, at Wimbledon, when the Belarusian won in three sets, 3-6, 6-2, 6-1.
Bacsinszky has a 4-1 head-to-head record against Makarova - but they have not faced each other since Madrid in 2016.
Mattek-Sands entered the tournament on a wildcard last year, and reached the Round of 16.
Puig and Stosur played each other most recently at the Australian Open - when the Olympic gold medalist emerged victorious, 4-6, 7-6(6), 6-4.
