LOS ANGELES — Andre Ethier’s grand slam capped an eight-run second inning that included six walks by Tim Stauffer — three with the bases-loaded — to help the Los Angeles Dodgers beat the San Diego Padres 8-5 Tuesday night. The Dodgers have won seven of their last eight, while the last-place Padres have dropped six in a row and lost six consecutive at Dodger Stadium. Hiroki Kuroda (11-14) allowed seven hits and four runs in six innings, struck out three and walked two to win his career-high fourth in a row.
