The games progressed smoothly and the technology was well-received — even by the umpires. "Since we found out more about it — how it's going to work, where it's going to work — I've had more positive feedback than I have negative," Dean Poteet, who worked behind home plate in one of the games, told the Associated Press.
Poteet was still busy even without making judgments on balls and strikes. He was responsible for fair or foul calls on balls in the infield, watched for balks, and made safe or out calls on plays at the plate.
