LOS ANGELES -- It appears quite likely that the Los Angeles Dodgers would bring Clayton Kershaw back on three days' rest if their National League Division Series with the St. Louis Cardinals lasts four games.For one thing, there's a precedent. Kershaw did just that with the Dodgers leading 2-1 over the Atlanta Braves last season, going six strong innings in their 4-3 win that sent them to the NLCS. For another, Kershaw threw a simulated game Sunday, four days after his final start of the regular season, a move seemingly intended to get his body used to short rest.
