Justin Verlander isn't worried about potentially tipping his pitches.

Verlander matched a career high by allowing nine runs on Saturday against the Cleveland Indians. He gave up 11 hits in four-plus innings, including a pair of home runs.

Brad Ausmus said Verlander and James McCann changed their signals throughout the game as a precaution against signs being stolen.

"We use multiple signs with nobody on base. We change our signs often. It's got to be something other than that," McCann said.

"For a day where I thought he had his best stuff all season, they seemed to be on quite a few pitches," McCann said. "What that is, I don't know. We're going to study film and see."

On Monday, Verlander tweeted a photo of himself drinking a beer in a pool with the caption, "working on my tipping."
