The BBC are obviously slightly annoyed that Murray’s high rating singles career is over, so are desperately clinging onto any scraps, including First Round Mixed Doubles, which would never be enough to rip up the prime time schedule, even with big name or UK players taking part.
I doubt they'd have done it if it wasn't for him playing with Serena. They'll at least get that bite of the cherry tonight.
Particularly as there isn't really another hugely successful British star worthy of shifting the schedules to replace him with, yet.
No big name but must say this is the first time I remember there being three Brits back to back on the show courts (one on Centre then two on Court 1) on the middle Saturday of the tournament, and arguably two of them there on their own merit rather than because of whom they're playing. The BBC not quite forgiven Dan Evans though after his ban for cocaine use and kept him on the red button and then BBC2 rather than on the main coverage today.
I preferred the internet when it had a sense of humour.
