how dose reuven's eye get hurt? could it have been prevented? do you think danny did it on purpose?

Reuven’s team is leading five to three, and he takes over as pitcher and baffles the first hitter he faces, Dov Shlomowitz, with his wicked curveball. Danny bats next and rings up two strikes as Reuven’s curve dives below Danny’s swing. Reuven then pitches two balls, but by Reuven’s fifth pitch, Danny adjusts to the diving action of the curve. He deliberately swings low and crushes a line drive back toward the mound. Reuven brings his glove to his face to catch the ball, but it hits the tip of his glove and bounces back onto his glasses, shattering them. While lying on the ground, Reuven imagines he sees Danny smiling at the injury. Reuven sits out for the rest of the game and watches his team lose eight to seven. After the game, Mr. Galanter calls a cab to take him to the hospital.
