Yes: Hit F11 twice.
The top center of the screen will show L= with the ping displayed, along with game seconds (T=) and display delay (+n), and FPS.
T=xxx(+y) where xxx is in-game seconds and y appears to be your display delay to game time.
L=xxx ms (a|b|c|d) where xxx is your ping, and abcd are (maybe?) your deviation from L (current, avg, max, min)(maybe?)
FPS is frames per second
Posting because I had this very question several days ago and only found this old reddit post that pointed at the icons next to the player scores instead.
