I suppose, in the heat of the moment, it's possible to forget that a pop-up is still playable when it is in foul territory. Once baseball players start running right at you, though, I kind of feel like you should know to get out of the way. Not this lady.
Joaquin Arias had to make a difficult play for the final out of the ninth inning in San Francisco Monday night, when the ball girl just forgot she's supposed to get out of the way. In fact, she actually asserts herself for a second and tries to catch the ball, as Arias speeds by her. Luckily, he made the play—though he did trip a bit on the ball girl's seat—and everyone can S their H and chuckle at the flustered (and very apologetic) lady in San Francisco.
The Giants lost to the Red Sox, 7-0.
