JUPITER, Fla. — As part of the homework he took into the offseason, Cardinals catcher Andrew Knizner used video to study dozens of late-game situations he did not get to call, did not get to see in person, but could still scrutinize for experience.
He would prep for the replays by researching the cold zones of hitters, the heat brought by the pitcher, and where the metrics might meet for a high-pressure out. An engineer major in college, he said, he likes numbers and wants them handy, just as he would for a game.
That is still his biggest variable.
