In a small storefront in Arlington, Lee is hard at work.
He's busy sewing the 2015 postseason patches on Texas Rangers jerseys.
"When they need somebody, real quick, yes, I'm the one to do it, " Lee said.
It's a job he's held for more than two decades.
If a player gets traded to the Rangers, Lee is in charge of getting his jersey ready.
For the post season, Lee will put new patches on roughly 350 game jerseys.
Each patch takes about five minutes to put on.
