Durant was accompanied by Thunder teammate Nick Collison, and both sat in the TV broadcast booth in the bottom of the second inning alongside Mike Krukow and Duane Kuiper.
Here are some Durant baseball facts: he played first base as a kid, he appreciates the intensity of Buster Posey, he made even the 6-foot-5 Brandon Belt look short and he admired the Giants' 2012 World Series run.
"You can take some things from them and put them into our game -- how they fought from being down, how they came together as a team," Durant said. "They've been playing on a championship level for a while now."
Bruce Bochy doesn't need a new first baseman, but it turns out he was a big basketball fan growing up.
"That was my love growing up," Bochy said.
Bochy was sure he would make his junior high team, but he was cut.
"That was the end of my basketball career," Bochy said.
As for Durant, he was asked whether he could he hit a curveball.
"I couldn't really hit any ball," Durant said.
Even so, it seems like it worked out for both of them.
