We were third in line at the gate, but the two people in front of me sort of got out of line by standing in front of another gate. So, I was first into the stadium. Upon entering, I found ball #1 in the right field seats. I watched helplessly as an usher picked up another ball I had spotted.
Travis Hafner batted at the beginning of batting practice and peppered the right field seats with home runs. I was able to grab ball #2 and ball #3 off of his bat within about the span of a minute.
It helped that the crowd looked like this for the first 30 minutes or so:

Season: 98 Balls (43 hit, 44 thrown, 11 device)
Games: 18 Games (15 with BP/ 3 without)
Average: 5.44 balls per game
