Story highlights The U.S. Virgin Islands holds its caucuses Saturday

Puerto Rico's primary is Sunday

Hillary Clinton is within 75 delegates of clinching the Democratic nomination

(CNN) Hillary Clinton inched closer to the Democratic nomination -- and putting further distance herself from Bernie Sanders -- in two island contests over the weekend.

The Virgin Islands had seven delegates on the line in its caucuses on Saturday and all went to Clinton. Then, on Sunday, Puerto Rico had 60 delegates up for grabs in its Democratic primary.

The contests essentially serve as a warm-up act for the big prize: Tuesday's slate of contests in California, New Jersey, New Mexico, Montana and South Dakota.

But for Clinton, who is just 60 votes short of reaching the 2,383 delegates she needs to clinch the Democratic nomination, the two weekend contests place her on the precipice.

Clinton currently has 2,323 delegates -- including 1,769 pledged delegates and 547 superdelegates. Sanders has 1,547 delegates total -- 1,501 pledged and 46 super delegates, according to the latest CNN estimates.
