Nine-year-old Braden Buehrle sang the national anthem before his dad's jersey retirement

It was a family affair during the ceremony for the retirement of Mark Buehrle's No. 56 jersey prior to Saturday's White Sox game against the A's. His daughter, Brooklyn, threw the first pitch to her father, who changed positions for the occasion.

Braden showcased his angelic soprano pipes to the people of Chicago.

The performance led to calls among fans to bring Braden into the fold as a regular anthem singer at White Sox games. His dad, however, was ready to get back home to Missouri -- he had a softball game to get to on Sunday night.
"I told them to be on standby because I don't know what time we are leaving," said Buehrle, who bats cleanup and plays first base.
Hey, with a swing like this, he's worth waiting on:
