Teoscar Hernández first felt something click with his swing last weekend.Mired in a miserable months-long slump, Hernández finally squared up on a ball during a recent game against the Detroit Tigers. It was corralled near the warning track for an inning-ending fly out, but the way the bat struck the ball also struck a chord of familiarity.Hernández had been searching for this feeling since straining his left hamstring near the end of May. After several maddening weeks, Hernández sensed he had found a breakthrough.“It’s just the way my body was reacting; it was more under control. I was able to notice everything that I was doing,” Hernández said. “That was the swing that is leading to all the good results that I’ve been having lately.”It’s hard to reach a better result than what Hernández and the Dodgers found Thursday night. The rebuilding St. Louis Cardinals were two outs away from sweeping the back-to-back champions. The Dodgers were clinging to life, with runners on first and second and one out.Enter Hernández, who had reached base in all four of his prior at-bats Thursday night. He worked the count full off Cardinals closer Riley O’Brien before hammering a payoff sinker, which was left in the heart of the zone. The ball exited the bat at nearly 106 mph, searing into the gap in left-center before rolling to the wall.Tommy Edman scored from second to tie the game. Mookie Betts followed from first to seal it. And there stood Hernández at second base, a combination of jubilation and relief, as the Dodgers walked off the Cardinals 3-2.“It was huge to finally get that big hit,” said Edman, who racked up four hits in the leadoff spot with Shohei Ohtani held out of Thursday’s lineup. “We were kind of pressing a little bit in those first two games. Everybody was kind of trying to do too much in the big spots.
