What's the deal with... stoppages of play after Jaime Moreno scores?

With five goals on the season, Jaime Moreno continues to set the League goal-scoring mark with each tally. At 34 years of age and with 117 total MLS goals, Moreno shows no sign of slowing down. You may have noticed that after each Moreno goal, the referee stops play so that the ball can be removed from the field for safe-keeping.
