Why is this one fixed?
Gil is better than Köllerer on hardcourt. This outcome was to be expected, even if it is Frederico's first match back in a long time.
He was a 1.65 fave before the match. A few minutes before that he dropped to 1.1 favourite.
He was still an overwhelming favourite when he was a break down in the first. He was 1.07 at 4-3, on serve.
No problem in assessing the matchup and agreeing that this is not a surprising win, but when you see these odd movements in the betting, then there is reason to be suspicious.
