Giselle Isabella Guillen: Predictions and form

Giselle Isabella Guillen. The record here is almost entirely on hard: 1-3. Too many free points go away on serve: 8.6 double faults a match, and the first delivery wins only 60.2%. A real threat on return: 84.1% of break points are converted. Point for point, 62.3% go this player's way.

A difficult stretch: 3 of the last 4 matches lost. No match in our data has lasted longer than the 30-game duel with S. Yoshida. Open any of these matches for BananaCore's pick, a predicted scoreline and the serve and return figures behind them. Latest tournament on record: ITF Women W15 Fukui.
