Wong, who leads the team with 15 hit-by-pitches, was struck first by Trevor Cahill in the sixth. It happened again with a Fernando Rodney pitch in the eighth, which led to both benches being warned. Wong made a point of walking slowly and deliberately to first base.
"I was pretty [upset] that not once, but twice I got hit," he said. "I don't know how to explain it, but I didn't like it."
Before the game ended, the Cubs also hit Greg Garcia, leading to ejections of Maddon and Hector Rondon.
