GAME NOTEBOOK: A large group of bees settled in deep center field at the start of the game and Pagan - the first batter - sent Arizona's A.J. Pollock into the swarm to make a running catch. The game was briefly delayed before the umpires determined it was safe to continue, and the bees were not a factor for the remainder of the game. ... Goldschmidt, who is 11-for-26 this season, owns the second-longest hitting in club history, trailing Luis Gonzalez (30 games in 1999). ... Pence snapped an 0-for-13 start to the season with a single in the fourth inning.
