Big hold by Liam to go 5-2. Ball was long at 30-15 but the umpire overruled the line judge and also awarded the point to Fritz should be a let! Lim lost the next point to face a break but then managed to hold with an Ace. Could have lost it with a call like that.
I think the call was indeed late so it's a judgement call but probably fair to call the point to Fritz iff it was indeed in but Liam clearly doesn't think it was. Great focus.
