Bit of contention in this match. At 3-3 in the last set Ball was 15-30 on serve, when the umpire half called out one of Johnson's shots. The umpire actually called "OU-" and then stopped very clearly.
Ball returned the shot, but looked at the ref who did nothing, and Ball mishit the next shot. He exploded at the ref, who advised he said nothing even though it was clearly captured on the stream
. Went ballistic, shanked his next shot the point after, sent the ball into orbit and, despite having breakpoints in the next game, the match.
