Bryce Harper felt some Washington Nationals fans crossed the line with their heckling in the eighth inning on Wednesday night.
"They were fine all game, talking about myself and things like that," Harper said. "I get it everywhere I go. That's nothing new.
"But the last two innings, it's just not right. It's not right."
Harper, who endured the Philadelphia Phillies' fifth-straight loss, said he was eager to get back to Philadelphia.
"I've got 60,000 fans up in Philly that appreciate me as a player, appreciate me as an individual and my family," Harper said. "I owe a lot to those people up there in Philly, because they show up for me every single night and they're there to cheer us on and boo us and keep us going as a team and as individuals, as well."
Harper played 927 games for the Nationals over seven years. He signed with the Phillies as a free agent before the season.
