Bit of a strange one this. Urb only won three points on serve in the first set - and they were in the last game. Holly has had a couple of bad service games though, so not totally dominant at the moment.
The JCH was almost a year ago, and the WR seems to be mainly from W15 clay court tournaments, including a couple of wins. Recent W25 matches haven't been that impressive so I'd give Holly a chance.
