Pitch tipping and sign stealing seem to be the hot topics of the 2025 MLB postseason.

But what one Mariners slugger did on Wednesday afternoon to seemingly relay signals to his teammates was a little too obvious, according to two former big leaguers announcing the game.

In the fourth inning of the Tigers’ 9-3 home win over the Mariners in ALDS Game 4, Josh Naylor was on second base with Detroit reliever Tyler Holton on the mound.

With Mitch Garver batting, Naylor held his arms in various positions before Holton delivered a pitch to the plate, either in an attempt to relay signs or make the Tigers think he knew what pitchers were coming.

Play-by-play announcer Adam Amin pointed it out early in the at-bat, telling viewers to “keep an eye” on Naylor’s arm motions.

"I don't like it."
