Kershaw (toe) threw a 30-pitch bullpen session Friday, David Vassegh of AM 570 LA Sports reports.
Manager Dave Roberts said that Kershaw's injured big left toe isn't at 100 percent, and the injury has prevented the veteran southpaw from executing pitches in a timely fashion, per Mike DiGiovanna of the Los Angeles Times. Kershaw may need another bullpen session or two before facing live hitters as he aims to return from the 15-day injured list before the start of the playoffs.
