WATCH | This week's Tennis Channel segment is dedicated to the sport's newest phenom: a 6-year-old monkey named Riki. (Full disclosure: Tennis Channel is owned by Circa's parent company, Sinclair Broadcast Group.)

Yoshiyasu Yoshizaki's YouTube channel shows the little fella in action.

Yoshizaki's channel has more than 110,770 views.

Yoshizaki also has 1,800 followers on Twitter.

Monday marked the one-year anniversary of Riki's tennis videos. So, of course, a video was uploaded to celebrate the occasion.
