ST. LOUIS -- It didn't take long for the Los Angeles Dodgers to grow tired of questions about their ace pitching on short rest.Clayton Kershaw did it for the first time in his career Monday and pitched six strong innings to set up the Dodgers' Game 4 win over the Atlanta Braves, but neither he nor manager Don Mattingly was interested in discussing it much before Game 1 of the National League Championship Series in St. Louis. It's less likely to happen this series, because Kershaw is pitching Game 2 and, if necessary, 6.
