Phillies hero Bryce Harper slammed by Braves announcers after he made 'throat-slashing' sign and stared down Orlando Arcia in MLB NLDS victory

Both times, as he made his way past second base, Harper stared at Arcia after the Braves star mocked him following game two of the series. Arcia was heard repeatedly joking: 'Ha-ha, atta-boy, Harper!'
