Terrill)LOS ANGELES Kik Hernndez homered and drove in five runs as the Los Angeles Dodgers beat the rival San Francisco Giants 8-1 in a fan-less ballpark as baseballs shortened season opened on Thursday night. Betts struck out swinging in his first at-bat a day after signing a $365 million deal over 12 years. Justin Turner grounded into a fielder's choice and Betts beat a throw to the plate to give the Dodgers a 2-1 lead in the seventh. Betts struck out with the bases loaded to end a five-run inning that made it 6-1. PREGAME CEREMONYThe Giants and Dodgers held a black ribbon that wound along the baselines in a show of unity after pregame introductions.
