Ramon Laureano of the A’s had one of baseball’s best plays of the year on Saturday. He tracked down a deep fly ball on the warning track in left-center field and then turned and threw it more than 300 feet in the air to get the runner out at first who had assumed incorrectly that the ball would drop and had already rounded second base. It was an almost superhuman throw, and the first baseman didn’t even have to stretch for it. It was like the ball was on a string right to his glove.
