Buster Posey was hit in the head with a fastball, and everything else is secondary. The sound was appalling, and the facial expressions were concerning, and he had to leave the game for precautionary reasons. After the game, Bruce Bochy suggested Posey was fine and had “no complaints” about specific pains or concussion-related symptoms. They’ll watch him closely and reevaluate him tomorrow.
On the surface, it seems like everything is fine, and we can enjoy the home opener. The Giants scored four times! Three of them came on one of the most embarrassingly silly plays in Diamondbacks history, which makes it one of the most wondrous plays in Giants history by default!
