SEATTLE (AP) — Seattle Mariners second baseman Dylan Moore’s season is over after he was placed on the seven-day concussion list Tuesday. Moore was hit in the head for the second time in a week, taking a 92 mph fastball from Houston Astros reliever Brandon Bielak off the helmet in a 6-1 win over Houston on Monday night. Moore remained in the game, but began to feel effects afterwards. Moore was also hit in the helmet by a 99 mph fastball from San Francisco Giants reliever Sam Coonrod last week.
