Yu Darvish allowed three hits over seven dominant innings, Wil Myers drove in five runs and the San Diego Padres extended their strong start with a 6-2 win against the Pittsburgh Pirates on Monday night. Darvish (1-0), acquired from the Chicago Cubs in December in hopes of helping San Diego chase down the World Series champion Los Angeles Dodgers, struck out six and walked one in a crisp performance as the Padres won their fourth straight. Myers hit a two-run homer to the bushes beyond center field in the sixth off 21-year-old reliever Luis Oviedo (0-1) to put San Diego in front to stay.
