Kike Hernandez 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 baseball's shortened season opened on Thursday night. Mookie Betts, who took a knee during the national anthem, went 1 for 5 in his Dodgers debut. Betts struck out swinging in his first at-bat a day after signing a $365 million deal over 12 years.
