As the national media jumps on the Javy Baez train, so do the people of Chicago in search of some new Cubs gear.

After Baez’s solo home run in Game 1 of the NLDS against the Giants, then his several defensive gems, capped off by driving in the game-winning RBI in the Game 4 clincher, Baez’s legend has evolved on the big stage. His strong performances at the plate for a relatively quiet Cubs offense in the NLDS was huge — he slashed .375/.412/.563, providing two decisive RBIs. Needless to say, fans can’t get enough of him.

So much so that Clark Street Sports, a chain with locations around the city and suburbs, has sold out of Baez jerseys. Store employee Katie Baker used one word to describe the past week: “insanity.”

“Baez is the only jersey that we are out of right now,” she said. “Kids and almost completely out of adults. We are starting to have to make them custom for people because we did not anticipate him selling as well as he did.”

Baez’s jersey in the online MLB shop is still in stock but marked as having only a “few left.” Catcher David Ross’ jersey is nearly out of stock as well. Baez is also among the top sellers from all teams, behind his teammates Kris Bryant and Anthony Rizzo, as well as David Ortiz and Jose Fernandez.

One store that still has plenty of Baez jerseys is Sports World Chicago, located across from Wrigley Field.

Store employee Tony De Luna said the store is “stocked to the gills,” and they’re not worried about selling out. Though he did say they’ve had to order more of the individual jersey letters, as they make custom jerseys in the store.

And the sharp increase in sales of Baez gear isn’t likely to stop as Game 1 of the NLCS begins on Saturday night.

“He’s en route to being the MVP for the World Series if they do clinch and win it,” De Luna said. “He’s got that hype just like Duncan Keith did [when he won the Conn Smythe Trophy during the 2015 Cup run].”
