Monday, with Cole Hamels fanning seven in seven innings, marked the club-record sixth straight time the Rockies reached double figures in strikeouts.
"It's been an issue here lately," Rockies manager Walt Weiss said.
The Rockies won two of the games, but three of the losses were by one run and another by two. The clear answer is to put the ball in play more often, although that prospect is muddied by the Rockies facing two of the Majors' top five pitchers in strikeouts (the Dodgers' Clayton Kershaw and Hamels) during this stretch.
"We don't want to strike out," Arenado said.
