ROTW Contest for Gift Certificates to Lucky Lou's on Ray and 101 in Chandler!

I have 4 gift certificates from Lucky Lou's to give away this week.

There are two ways to enter the contest:
1. Find me at the field and tell me the answer.
2. Post the answer as a comment on the video that provides the answer to the question on the Leisure Sport Blog. The link to the blog is:

Question:
When has the base runner tagged up and is eligible to leave the base and advance to the next base?

There will be two winners from each way to enter the contest!
The first two players to find me at the field and tell me the correct answer will win one gift certificate each.
The first two players to comment on the correct video on http://leisuresport.blogspot.com/ will receive one gift certificate each.

I will see you on the field.
