Clayton Kershaw is a likely possibility to start Game 4 of the National League Championship Series for the Los Angeles Dodgers if the left-hander's back continues to improve, manager Dave Roberts said Wednesday. Kershaw was scratched from the Game 2 start because of back spasms, and Roberts decided to stick with left-hander Julio Urías for Game 3 against Atlanta on Wednesday night. Game 4 of the neutral-site series in Texas is Thursday night.
