Two weeks ago Nathan Patterson was at Coors Field to watch a Rockies game and turned heads by throwing 96 miles-per-hour at a speed pitch challenge. His throws were posted on social media and the Oakland A's ended up seeing him throw the ball that fast. Patterson got the call this week from the Athletics after they saw the footage and signed him to a contract. It’s unclear where Patterson will start playing, or when but this isn't the first time the A's had seen him throw.
