Anthony Rizzo came to the ballpark Friday with his curly hair straightened out, drawing lots of stares from his teammates.

Then he went 0-for-5, leaving him 0-for-18 on the road trip and hitless in his last 22 at-bats.

On Saturday, Rizzo reverted to his normal hairstyle.

Why did he change on Friday?

“Just to mess around, to get some laughs, have a good time,” he said.

Would he have kept it had he gone 4-for-4?

“Nah, too much work,” he said.

Rizzo is in a bit of funk, watching his average drop to .249. Is he pressing?

“We can always call it different things,” manager Dale Sveum said Friday. “But there’s definitely an urgency to where he’s not taking his walks, he’s kind of swinging and guessing, a lot more movement than he normally has at the plate.”

Rizzo said Saturday that “everything spirals into (the movement). You try to do too much…. It’s part of a season. Obviously this isn’t the worst thing I’ve ever gone through. I just have to keep working, keep battling.”

In one at-bat Friday, Rizzo slammed his helmet down after popping out on a 3-0 pitch.
