The Los Angeles Dodgers' slump hit a new low Friday night in Phoenix. Ryan Waldschmidt crushed a 411-foot, two-run walk-off home run off closer Edwin Diaz in a thrilling 4-3 Diamondbacks win, extending the Dodgers' losing streak to seven games. Over that six-game skid, Los Angeles was outscored 42-22, a stretch that continued Friday. Diaz, whom the Dodgers signed over the winter specifically to shore up a shaky bullpen, joins a broader relief corps that has struggled through the skid. Roki Sasaki started for Los Angeles and continued his strong recent form, but it was not enough to prevent the walk-off.
