Being more positive is paying off for former No. 1 Naomi Osaka early in her clay-court season. Osaka kicked off her clay campaign with a comfortable 6-3, 6-1 win over qualifier Anastasia Potapova in the first round on the Madrid Open center court on Friday. 

Australian Open finalist Danielle Collins won the last eight games to advance 7-5, 6-0 over Monica Puig, the Olympic gold medallist in Rio de Janeiro in 2016. 
Puig is returning to action following shoulder and bicep surgeries.
