Both players have demonstrated distinct strengths in recent form, with Diallo slightly outperforming on second serves, while Harris shows superior skills in return games, particularly on opponents' second serves.
When under pressure, Diallo appears slightly more dependable, saving a higher percentage of breakpoints than Harris. However, in terms of head-to-head competition, Harris holds the upper hand with a historical victory over Diallo.

Although Diallo boasts a stronger overall win/loss record in the last year, Harris's past success in head-to-head matchups and better recent return and breakpoint conversion stats suggest that Harris might have the edge in their upcoming contest.
Prediction: Harris is likely to secure a victory in this upcoming match, building on past successes and current performance metrics.
