Giants ballgirl tries to call off Joaquin Arias on a foul pop, might think she's playing

The Giants were down 7-0 to the Red Sox at AT&T Park on Tuesday night. They needed one more out to finish off the top of the ninth and mount a possible comeback in the bottom half of the inning.

The Giants ballgirl knew this. She wanted that out badly. So badly that she tried to call off Giants shortstop Joaquin Arias on a foul popup. Great try, Giants ballgirl -- but no. That's never your ball.
