The newest professional hockey team in the United States is leading the series for the championship of North American hockey. The Vegas Golden Knights of Las Vegas, Nevada, defeated the Washington Capitals of D.C., Monday night in Game One. The score was 6 to 4. The Stanley Cup Finals is a best of seven games series. The Knights began its first season last October. At the time, Las Vegas was recovering from the worst mass shooting in the U.S. On October 1, an attacker on a high floor of a Las Vegas hotel used a military-style assault rifle to shoot at a concert crowd below. The gunman killed 58 people and wounded more than 700. He then killed himself. Bill Bradley is with the sports department of the Las Vegas Review-Journal. He said the Golden Knights worked to help the city recover.
