Very poor umpiring in the Andreeva vs Stakusic match. Andreeva getting ready to receive, insects (bees?) flew around Andreeva before Stakusic served. Andreeva started standing straight up abandoning her ready position and started squatting the insects away while raising her left arm to signal "hold, not ready". Then, Stakusic's serve arrive to Andreeva and Andreeva casually just tap it away. Umpire gave the point to Stakusic and also claiming didn't see Andreeva's signal to hold. It's not Andreeva's fault that Umpire didn't see. Replay clearly showed Andreeva getting bothered and shooing away the insects. Argued briefly with umpire - umpire is adamant, won't budge. Andreeva turn around started crying and eventually turned around ready for the next point. Extremely poor umpiring.
Why can't tennis start reviewing such thing - even with automated line call - as this is not a line call.
