It seemed like the Phillies closer escaped the jam after Andy Pages struck a grounder towards him.However, Kerkering bobbled the grab and made a misdirected throw to his catcher, J.T. Realmuto. As the Phillies catcher failed to grab the ball, Hyeseong Kim dashed from third base to clinch a walk-off win for the Dodgers.Fans reacted to the Phillies closer's game-deciding error in extra innings."Now we can say that pitchers are not athletic.

Tough one to go out on."Paul Todd @CarmodyDenisLINKAs tough as that is, I feel for the guy. He muffed it and then panicked. If he goes to first we’re still watching in the 12th.

This play will haunt him forever."The Mighty Fetta @MightyFettaLINKHorrible decision! Always go to first!! Especially if you boot it!! Yoh can tell he knew it was a mistake right away and that’s why it flew but it was too late to change. This play will haunt him forever.Kerkering's mistake got him into the record books, for the wrong reasons, as the Dodgers became the first team to win a postseason series on a walk-off error.Rob Thomson, Dave Roberts sympathize with Phillies closer after Dodgers' walk-off winOrion Kerkering seemed heartbroken after his mistake ended the Phillies' postseason journey. He was consoled by Phillies manager Rob Thomson in the dugout.“Just keep your head up. He just got caught in the moment a little bit,” Thomson said. “Coming down the stretch, he pitched so well for us, and I feel for him because he’s putting it all on his shoulders. But we win as a team and we lose as a team.”Although the Dodgers benefited from Kerkering's error, manager Dave Roberts felt for the Phillies closer."It's brutal," Roberts said. "Obviously they played great defense tonight. It's one of those things that it's a PFP, a pitcher's fielding practice. He's done it a thousand times. And right there he was so focused, I'm sure, on just getting the hitter and just sort of forgot the outs and the situation. Kerkering is a stud. And you definitely feel for a player.''The Dodgers have qualified for the championship series for the fourth time in six seasons and will face the winner of the Chicago Cubs-Milwaukee Brewers series.
