"Phillies Reliever's 'Atta Boy' Shirt Celebrates NLDS Win Over Braves Amid Harper-Arcia Drama"

Philadelphia Phillies rookie reliever Orion Kerkering celebrates the team's NLDS win over the Atlanta Braves by wearing a shirt that reads "Atta Boy Harper" on the front and "He wasn't supposed to hear it" on the back, referencing comments made by Braves shortstop Orlando Arcia about Bryce Harper. Arcia had mocked Harper after he was doubled-off in Game 2, leading to a confrontation between the two players in Game 3. Kerkering, who has been impressive in the playoffs, did not pitch in Game 4 but has made a strong impact in his postseason appearances.
