Zack Greinke earned the NL ERA title and the Los Angeles Dodgers beat the San Diego Padres 2-1 Saturday night to clinch home-field advantage in their upcoming playoff series against the New York Mets. The Dodgers' win combined with Washington's doubleheader sweep of the Mets (89-72) ensured Los Angeles (91-70) will open the Division Series at home Friday against New York starter Jacob deGrom. Greinke (19-3) allowed one run and four hits in eight innings to conclude the regular season with a 1.66 ERA, beating out Cubs ace Jake Arrieta, who finished at 1.77.
