Quick Take

Pre-match view

Context last updated 28 Jun 2026, 08:59 · Europe/Bucharest

Solana Sierra's superior grass record (8-4 vs. 2-7) and recent form give her a clear edge over Anna Bondar in this Wimbledon opener.

Back Sierra to win in straight sets at 2.25, and consider over 20.5 total games given both players' tendency for tight matches. Avoid Bondar to win 2-1 at 5.00 due to her poor grass history.
