The Astros' electronic sign-stealing scandal rocked MLB right before the 2020 season, with the league's Jan. 13 investigative report revealing that Houston used a live-feed center-field camera in 2017 and at least part of '18.
As teams like the Mets and Yankees prepare for their return to the diamond in the spring, they naturally have a guard up with preventing sign stealing from runners on second base.
Breaking down examples on Wednesday's Baseball Night in New York, SNY's Anthony Recker and Todd Zeile explained to Doug Williams and Andy Martino how pitchers and catchers keep opposing teams guessing by mixing things up.
"I tried to formulate these and kind of condense the words so it'd be easy to fit on a card," Recker said. "Chase the 2 is exactly that. I'm going to put down a set of sequences. I'm going to put down several numbers. As soon as I put down the two, it's going to be the next sign after the two -- it's going to be the sign that I'm using in that sequence.
"You can add an extra variable and say, 'If I don't put down a two, it's a two.' So you can play with people, the runner on second base."
