Heliot Ramos, Rafael Devers and Wilmer Flores homered off Nestor Cortes in the first inning and the San Francisco Giants beat San Diego 4-3 to hand the Padres their fourth straight loss.

The Los Angeles Dodgers swept the San Diego Padres in the three-game series at Dodger Stadium. Yu Darvish gave up four runs in the first inning, and the Padres were left clawing back and did so, tying the game up at four in the eighth inning. However, Dodgers shortstop Mookie Betts then hit a go-ahead home run that clinched the series.

LOS ANGELES — It was touted as the biggest series of the month. It was billed as a potential passing of the torch, with the San Diego Padres threatening to win the National League West for the first time in 19 years. Instead, Sunday’s finale ended in a three-game sweep — and a relatively convincing one, at that.

With their three-game sweep of the San Diego Padres, the Dodgers proved they are deeper and more focused than their budding NL West rivals.
