It’s a telling and somewhat unfortunate aspect of the modern Major League Baseball broadcast — the manager reaction shot.
It rarely happens after something positive occurs because the broadcast director prefers cameras that focus on celebrating players’ elaborate handshakes or mugging for the camera.
But when a reliever gives up a home run or a fielder commits a costly error, at least one camera focuses directly on the manager to see his reaction. They want to see anger, disgust, a despondent head shake or perhaps a few curse words. To their credit, most managers have realized the focus turns to them, so they rarely have huge outbursts.
