In an event designed to highlight the home run, Cardinals outfielder Jordan Walker won it on the most exciting kind: a walk-off.From the get-go, Walker’s easy swing made for a fun contrast in style to Red Sox first baseman Willson Contreras, whose violent twists looked more like attempts to fracture the sky. Coincidentally, both finished the first round tied for first with 13 home runs.The drama of the night started when Phillies teammates Kyle Schwarber and Bryce Harper were up to bat (which was last) in the first round. As fate would have it, Schwarber hit 10 home runs to rank fourth — with only four hitters advancing — and only Harper yet to hit. It was going to be one or the other, and Harper ultimately came up short with eight, bowing out in the first round along with Ben Rice, Munetaka Murakami and Jac Caglianone.After beating Contreras and Junior Caminero head-to-head in Round 2, it was Schwarber and Walker in the final round. Schwarber went first and found his groove almost immediately, finishing with 11 home runs.That was a tall order for Walker, who hit just six home runs in his first 12 swings. But then came the magic. It went like this:Swing 13: home run (No. 7)
