Context last updated 31 Oct 2026, 19:16 · Europe/Bucharest

Two players three ranking places apart, but the form is not close: Staeheli has won eight of 12 hard-court matches, while Imamura has lost his last six in straight sets.

Staeheli is the likelier winner of this qualifying opener. At 1.55 he is the one price worth taking — it needs 64.5% and reads 68%; Imamura at 2.3 needs 43.5% against a 32% reading and does not.

Context

Low-profile Challenger qualifying between players ranked 430 and 433, with no research context or head-to-head history and modest samples on both sides; one quoted price carries a small margin.

Imamura has been starting matches on the back foot, winning only four of 14 opening sets in the sample.
Eight 0-2 defeats in 14 hard-court matches mean his matches have tended to end quickly once the opener slips away. Against Staeheli, that makes the first set the clearest signal: another early loss and the straight-set route becomes the likely path. The sample covers roughly eleven weeks and 14 matches, small enough that a couple of tight sets could shift the picture.
- Set sample: 14 completed hard-court matches, 11 August to 27 October 2026.
- First sets 4-10, second sets 6-8; scorelines 0-2 eight times, 1-2 twice, 2-0 four times; total games average 19.1.
Staeheli's first-set record in that sample is 4-8 while his second sets are 8-4, so his wins have tended to follow a slow start.
Eight wins in 12 hard matches is the stronger record in this matchup, but the even spread of scorelines shows how often his matches either go the distance or slip away. The 4-8 first-set split is the part Imamura can attack. Two retirements were excluded, so the 12-match base reflects completed matches only.
- Set sample: 12 completed hard-court matches, 13 September to 25 October 2026, 8-4 record, two retirements excluded.
- Scorelines: four 2-0 wins, four 2-1 wins, four 0-2 losses; first sets 4-8, second sets 8-4; total games average 21.2.
That result sits awkwardly against an 8-4 hard-court sample and is the clearest reason to treat his form as unsettled rather than dominant. It was a single match, played a week before this qualifying opener, so it does not erase the broader record. It does show his level can drop sharply against a lower-ranked opponent.
- On 25 October 2026, Staeheli lost 2-6 2-6 to Mikalai Haliak, ranked 898, on hard courts.
