It sure feels like the Dodgers have flipped a switch. An action-packed eighth inning provided the momentum shift the Dodgers needed to cap off a three-game sweep of the Nationals with a come-from-behind 7-5 victory on Sunday night at Dodger Stadium. Mookie Betts played the hero in the series finale, smacking a go-ahead three-run homer to put the finishing touches on the pivotal frame. L.A. has won four straight on the heels of a stretch in which it lost six of eight. At last, the Dodgers feel like they are playing to their capabilities once again. "We try not to have a switch because a switch doesn't really work that way," Betts said. "It needs to be our identity, and so I think we’d like for it to be our identity, and playing good ball all the time." Here's a look at each key moment from the eighth inning on Sunday night: **Tucker brings one back** Entering the eighth inning, the Nationals held a one-run lead and looked to be on their way to salvaging the finale. It looked like Washington was about to pad its advantage when Harry Ford led off the frame with a drive to deep right field, only for right fielder Kyle Tucker to make a leaping snag at the wall, robbing Ford of a likely homer. "I think it's a huge momentum-builder right there," said right-hander Bobby Miller, who was on the mound. "It's a big sigh of relief."
