​PHILADELPHIA — Jordan Walker just delivered the most impressive buzzkill in Home Run Derby history.The Cardinals’ outfielder, in the midst of a breakout season, needed to smash homers on six consecutive swings to come back in the final against hometown favorite Kyle Schwarber. With a sold-out crowd booing his every move, that’s exactly what he did.AdvertisementAdvertisementAdvertisementEach long ball off Walker’s bat pushed what was a cauldron of noise closer and closer to sounding like an abandoned library. The tension grew and grew. Schwarber, surrounded by a throng of Phillies teammates beyond the first-base dugout, slowly realized that Walker simply wasn’t going to lose.As the sixth and final blast left Walker’s Iron Man-themed lumber, he raised the bat above his head with two hands, a look of sheer disbelief on his face. Then he erupted.“COME ON, BABY!” he hollered toward the heavens before galloping over to the other Cardinals assembled at these All-Star festivities.For Walker, a former top prospect who struggled mightily over an extended stretch before finally coming into his own this season, it was a celebration years in the making. Not even four months ago, the 24-year-old seemed closer to “bust” than Home Run Derby hero. Now he has 22 home runs at the All-Star break for a surprisingly in-the-mix Cardinals team.AdvertisementAdvertisementAdvertisementAfter his victory Monday, Walker’s parents, Derek and Katrina, donning jerseys that read “Jordan’s Dad” and “Jordan’s Mom,” went ballistic in the stands as a supremely disappointed Philadelphia crowd headed to the exits.”I was once told you don’t boo nobodies, so it feels pretty good,” he proclaimed on the broadcast when asked how it felt to be booed by 40,000.While the night was a tough bounce for the city of Philadelphia, it proved to be a massive win for MLB’s new Home Run Derby format. This year’s edition was the first streamed exclusively on Netflix, which prompted a reworking of the event’s structure. The Derby clock, in place since 2015, was nixed in favor of a swing-based format: 20 hacks in the first round, 15 in the semifinals and finals.AdvertisementAdvertisementAdvertisementHowever, a player who went deep on his final opportunity could continue swinging for the fences. The thought was that if a guy caught fire and crawled his way out of a massive deficit, it would make for phenomenal theater.Well, Rob Manfred should toss Jordan Walker (who is earning $799,400 this season) more than the $1 million in prize money he took home on Monday. Because the new format was looking like something of a dud until Walker more than delivered, cranking four stunning blasts on his final swing.With Netflix streaming the event, MLB also went full camp for this Derby. The pregame festivities featured players emerging from sedan-sized, cardboard liberty bells as legendary PA announcer Michael Buffer bellowed the introductions. Each contestant strolled across the inf
