Hyun-Jin Ryu got himself on track, and the Los Angeles Dodgers used the long ball to get their five-game homestand off with a win. Ryu cruised through six innings of one-hit ball, Corey Seager hit one of three Dodgers homers and Los Angeles beat the Oakland Athletics 4-0 on Tuesday night. Ryu (1-0) rebounded from a rocky season debut to shut down Oakland.
