It’s not hard to figure how what was going on when Giants starter Jeff Samardzija sent a fastball to the backside of Arizona Diamondbacks slugger Paul Goldschmidt.

That’s how baseball tradition goes. When Buster Posey got drilled in the head Monday by the D-backs’ Taijuan Walker, intentional or not, pay back was going to come at some point.

While both manager Bruce Bochy and Samardzija stayed mum on the topic after Tuesday night’s game, broadcaster Mike Krukow was more open when he joined KNBR on Wednesday morning.

“It how you deal with it,” Krukow said of Samardzija drilling Goldschmidt, Arizona’s best player. “You cannot allow your opponents to hit you, and when you get a head shot, whether it was intentional or not, it doesn’t matter. It happened, and not only that it took down your best guy, and put him on the shelf for at least a week. All those things are things that cannot happen. And it’s been a part of the game for a long time.”

“I’m from that generation, you got one of ours, we got one of yours. Simple. You get it done, it’s over, and they got it done. And Samardzija, to his credit, he got it done right. It was below the belt. He put a bruise on Goldschmidt’s butt, it’ll sit there and it’ll be a little soft advertisement for the team for a couple weeks, depending on how good of a bruiser he is. It’s just a little reminder that this is how the game is played, and you move on. I hope there’s no repercussions in regards to the league office fining Samardzija because that always frosts me when it happens, but it’s done, it’s over. And it was done right and it was done in a professional way.”
