As soon as the first inning ended, Rockies third baseman Nolan Arenado came into the dugout and began yelling in frustration.

The Rockies had been shut down by former teammate Drew Pomeranz in the top of the inning and gave up Matt Kemp's three-run home run in the bottom.

"Just frustration got the best of me," Arenado said after the Rockies lost 4-0 Friday night, their third straight defeat and sixth loss in seven games. "If I was going to do that I probably should have done that in the tunnel. I got frustrated, I let it out. The boys know I love them. I wasn't yelling directly at anyone. Just losing is getting old."

Said manager Walt Weiss: "He was frustrated. He cares. He wasn't directing it at anybody. He was just kind of pacing in the dugout. Not a big deal. He was just frustrated. You let him have his say and then move on."
