It was a streak of bat luck. The Nationals’ six-time All-Star narrowly beat Cubs slugger Kyle Schwarber 19-18 in the final round on Harper’s Washington, D.C., home turf. Each batter was allotted four minutes to hit as many homers as possible. Harper, sporting patriotic swag, slammed 45 total — including nine in his final minute to tie Schwarber, and one in a tense bonus round — on pitches from his dad. The total set a new Home Run Derby record of 221 longballs ahead of today’s All-Star Game.
