Sandoval explained that he lost the ball in the Minute Maid Park lights.
"So I just guessed [where it was]," he said.
Since Sandoval couldn't grasp the ball, he did the next best thing: He kept the play alive by batting the ball upward, falling as he did so, as if he were a volleyball player executing a "dig."
Said Sandoval, "I tried to just hit it high."
Sandoval had no idea that Crawford was nearby.
"I couldn't believe he was there," Sandoval said.
"It was a popup in no-man's land," Crawford said. "If it's a little bit more over his head, I'm calling him off."
Hovering near the foul line and about five feet away from Sandoval, Crawford took a couple of quick steps before launching himself forward and clutching the ball with two hands as he fell.
"I reacted. I saw the ball in the air," Crawford said.
"It was a little see-saw effect. You didn't know what would happen," said right-hander Matt Cain, who watched the drama unfold from the mound.
The Giants were properly impressed.
"It might be the best play I've ever seen," Romo said. "[Sandoval] smacked it twice in the air, then homeboy [Crawford] comes down diving. It's pretty sweet."
"I don't know if I've ever seen that," said manager Bruce Bochy, who entered professional baseball in 1975.
Even the typically humble Crawford gave himself a positive review.
"It looked better on the replay," he said.
