Los Angeles Dodgers catcher Yasmani Grandal is the latest player to complain about opponents stealing signs.

Grandal said the Cubs stole signs during Game 1, so he was forced to switch up the signs multiple times in Game 2.

“We are literally paranoid when it comes to men on second and they are trying to get signs,” Grandal said per the LA Times. “We know who is getting the signs. We know what they’re doing. We know what they do to get it. In the playoffs, one relayed sign could mean the difference between winning the World Series and not getting there.

“That’s why we have four or five different sets of signs, and we’re constantly changing.”

Grandal named a specific instance in which he noticed the Cubs attempting to steal signs. When Ben Zobrist doubled to lead off the eighth inning of Game 2, Grandal says the Cubs infielder tried relaying signs to batter Addison Russell.

“All the sudden, Russell is not taking good swings at sliders, looking like he’s looking for a fastball and in a certain location,” Grandal said. “Did we know Zobrist had the signs and was doing something for it? Yeah, we did. That’s why we do it.”

Stealing signs and other circumstances have been an ongoing topic of discussion this postseason. The Boston Red Sox accused the Cleveland Indians of stealing signs throughout the ALDS.

It’s not like sign stealing is some crazy new epidemic in baseball. Teams do it all the time. It’s up to the pitcher and catcher to switch them up in order to prevent it from happening. Obviously that’s what Grandal and Kershaw did in Game 2, but they should’ve done it without all the whining.

If your signs are that easy to steal, it’s your problem, not your opponent’s. Quit complaining and figure it out.
