Derek Norris was stunned by his ninth-inning at-bat Tuesday.
It wasn’t because the A’s catcher homered against Reds’ left-hander Aroldis Chapman, perhaps the hardest-throwing pitcher in the game.
It was because the ball didn’t carry farther than it did. Center fielder Shin-soo Choo went back to the wall in center field and never had a chance for the ball. But the mere fact that Choo felt the need to retreat puzzled Norris.
