Editorial Prediction (May 21, 2025, UTC):

As we evaluate the upcoming match, Back holds distinct advantages in several key statistical areas. Their strong second serve performance, superior return game strategy, and consistent success under pressure highlight Back's strategic edge.

Although Jeong shows a slight edge in first serve return effectiveness, Back's ability to convert breakpoints provides an edge in critical match situations. The overall performance over the last year strengthens Back's case as the favorite, coupled with a recent victory over Jeong on a similar surface.

Given their higher success rate in deciding sets and breakpoint scenarios, Back is poised to leverage these strengths for a likely victory in this matchup.

Considering these factors, Dayeon Back is expected to emerge victorious in their upcoming tennis match against Jeong.
