Quick Take

Pre-match view

Context last updated 26 Oct 2026, 15:18 · Europe/Bucharest

Chung is the likelier winner in this Seoul first-round hard-court match, but the 1.55 on him does not offer value, and the 1.60 prices on him to take the first set and the second set are also worth passing.

The one worthwhile quote is Imai to win 2-0 at 3.8; his straight-set wins and Chung's occasional 0-2 defeats give that exact scoreline a real case, even though Chung remains the likelier match winner.

Context

Across 15 completed hard-court matches from 10 July to 26 October 2026, Imai won six times 2-0 and once 2-1, while losing five times 0-2 and three times 1-2. His matches average 2.27 sets, so straight-set results have been the norm in both directions. The 2-0 pattern is therefore grounded in his own scorelines, but it remains a 15-match sample and does not by itself make him the match favourite.
- Home set evidence covers 15 completed hard-court matches from 10 Jul 2026 to 26 Oct 2026, with 0 retirements excluded.
- Imai's scorelines in that sample: 2-0 six times, 2-1 once, 0-2 five times, 1-2 three times.
- His total sets average is 2.27 sets per match.
Across 12 completed hard-court matches from 22 August to 27 October 2026, Chung played just one match with a tiebreak; the sample excludes three retirements. His first sets average 8.83 total games and his second sets 9.42 total games. The pattern is notable for how short his sets have been, but a 12-match sample is small and the retirement exclusions leave some uncertainty.
- Away set evidence covers 12 completed hard-court matches from 22 Aug 2026 to 27 Oct 2026, after excluding three retirements.
- Only one of those 12 matches included a tiebreak.
- Chung's first sets average 8.83 total games; his second sets average 9.42 total games.
