Halep gives coach Cahill a taste of his own medicine

In an opportunity for revenge that any tennis player would have happily taken, Simona Halep switched places with her coach, Darren Cahill, in a video for Wilson, with Halep being the coach and Cahill being the player.

The world No. 1 issued Cahill command after command, and finished the session with the world's worst feed.

"Do I talk to you like that?" Cahill asked, getting a "yeah" response from Halep.

Halep is currently in second in the 2018 Race to Singapore, though she's cooled of significantly since her strong start to the season, having not reached a final since the Australian Open.

Kicking off her clay season, she fell in the Stuttgart quarterfinals 6-4, 6-1 to eventual runner-up CoCo Vandeweghe.
