Geukens seems to have a ranking that is very much based on a successful spate of futures in Sharm at the back end of last year. But not a whole heap of success since then....Emily W-S beat her easily in Feb. of this year. And she took three close sets to beat Tiff William in Portugal a couple of months back.
Unlike Geukens who, as above, seems to have a very 'fragile' ranking, Uzcategui seems to be a slightly stronger player with a good run last week in the 25k, beating a top 300 player to make the quarters, and a long time without tournaments, having not played between Feb. and June, so obviously not with the normal amount of points she'd have got otherwise.
