Chris Bosh performs coin toss at Miami Open

Usually the coin toss is done by a sponsor representative or local child, but in Miami, players got to meet Chris Bosch instead.

The former Miami Heat basketball towered over Felix Auger-Aliassime and Borna Coric ahead of their quarterfinal match. He also spent some time with tournament director James Blake.

Bosch was a 2003 NBA draft pick and began playing for the Miami Heat in 2010. His No. 1 jersey was retired just recently in a special ceremony, also on Wednesday.

Auger-Aliassime went on to win the match, 7-6 (3), 6-2 despite saying he was "low key tight playing in front of this legend."

He plays defending champion John Isner for spot in his first ATP Masters 1000 final.
