Sectional 1-0 controversy

[umpjong]

"During the controversy, Elder second baseman Selby Chidemo noticed Marcano had not touched first base and he went over and stepped on the base with the baseball in his glove. One of the umpires then ruled Marcano out. Marcano eventually left his group and touched first base in hopes of completing the play."

This sounds to me like he wasnt just delayed a second or two. Would like to see in real time, but "eventually left his group" and the time it would have taken F4 to retrieve the ball and go to first and get the umpires attention.....
Unless this sequence was less than a couple of seconds, I still have an out.... How long are you going to let him celebrate, and make the defense wait to appeal?
