The Miami Open iguanas are back

Just when the hoopla created by Iggy (or Iguanacho) the iguana has died down, his friends return. Roger Federer's Miami Open practice was crashed by a smaller version of the giant lizard, who probably just wanted an autograph.

And Kristina Mladenovic was also paid a visit.

She got in a little extra running:

They still both seemed to enjoy the show more than Jiri Vesely did when his match with Tommy Haas was paused in the third set to rid the court from a rogue iguana.

Luckily, Haas embraced his new friendand line umpire Frankie Melendez was brave enough to handled the situation.

There's a full week of action left in Key Biscayne—plenty of time for more unexpected guest appearances.
