Trailing in the second set, Harris kept up a steady stream of dialogue with the only person in the stands he could  his coach, Anthony Harris (no relation). Rafael Nadal was heckled by a woman who yelled and waved her middle finger as the 20-time major winner prepared to serve in his second-round win over Michael Mmoh. Other sounds not normally heard also felt amplified: the creaking of electronic sunshades rising into position on changeovers, the pitter-patter of the ball kids shoes. Mackenzie McDonald said he and his third-round opponent, Lloyd Harris, were both confounded by an odd beeping sound they heard as they played on Court 3. This doesnt make it easier, though.
Michael Mmoh is in the ironmentary school of change.
