Umpires overturn Norris' double into a home run

OAKLAND -- The difference between a six-run A's lead and an eight-run advantage in the sixth inning of Oakland's contest with the Angels on Tuesday rested in the eyes of the umpiring crew.

Oakland was awarded the extra pair of runs, after the call on Derek Norris' double was overturned upon review, and ruled a home run, making the score 8-0.

The A's catcher picked up his fourth home run of the season, as his shot to left field barely eclipsed the line above the out-of-town scoreboard.

Adam Rosales followed Norris' long ball with one of his own, his first of the year, to extend Oakland's lead to nine over the visiting Halos.
