WATCH: Kyrgios, Dimitrov sign camera with cryptic shapes

Things have been getting weird on the ATP Tour lately. Last week, Thanasi Kokkinakis and Hyeon Chung went all in on a blond trend, and, now, the customary post-match camera-lens signatures have been getting replaced with cryptic shapes.

It started with Nick Kyrgios, who does everything in his own way. After his 7-5, 6-3 win in Miami on Friday over Alexander Bublik, Kyrgios, for reasons completely unexplained, autographed the camera with a triangle.

Then, on Saturday, Grigor Dimitrov, in the same PlayStation-esque fashion, signed it with a square and sealed it with a kiss.

It's hard to tell where this trend is going—there being only so many shapes to choose from before players have to get extra creative—but time could easily tell, as both Kyrgios and Dimitrov have unseeded opponents next.

Kyrgios went on to beat Dusan Lajovic on Sunday, and signed the camera with a bunch of lines and a smiley face. Dimitrov fell in the third round to No. 77 Jordan Thompson.
