Kershaw threw 94 pitches over seven innings, allowing just a run on three hits while striking out eight. The lone blemish was a solo shot from Mets second baseman Daniel Murphy in the fourth.
Kenley Jansen entered in the eighth and recorded a five-out save, working out of a jam in the eighth and tossing a flawless ninth.
The series will head to Los Angeles for a deciding Game 5 on Thursday at 8:07 p.m. ET.
