Major League Baseball is reviewing Washington Nationals slugger Bryce Harper’s confrontation with home plate umpire Brian Knight during the bottom of the ninth inning of Washington’s 5-4 victory over the Detroit Tigers on Monday. Knight ejected Harper from the Nationals’ dugout after Danny Espinosa was called out on strikes. Moments after pinch hitter Clint Robinson hit a walkoff home run, Harper ran out onto the field to celebrate and pointed at Knight and cursed at him. MLB senior vice president Joe Garagiola Jr. will confer with chief baseball officer Joe Torre and others to determine whether any punishment is warranted. After the game, Harper described what he said as ‘‘a couple choice words.’’ When the possibility of a fine was mentioned, Harper said: ‘‘If I do, I do. I’ll pay it. Maybe [Knight will] get fined, too. So we’ll see.’’
