Serena Williams just lost to Japanese Naomi Osaka in the 1st round of the Miami Open. Osaka won 6-3, 6-2.
Osaka is coming off her Indiana Wells tournament victory on Sunday. It appears that win energized her and set her up to beat the former World number 1.
Serena, of course, became a mother less than a year ago and is surely looking for more practice before she is in pre-pregnancy form.
The match was much closer than the score indicates.
