Clayton Kershaw struggled against the St. Louis Cardinals last postseason, but the left-hander and likely NL CY Young winner, isn't dwelling on the past.

The Cardinals moved onto the World Series last fall by beating the Los Angeles Dodgers 9-0 in a game that Kershaw started.

"Clayton is going to use everything as extra incentive all the time," Don Mattingly said. "I think probably that game fueled him all winter in his training. Then, when he had a bad game early in the year against Arizona, I'm sure he used that. I think he's always on the hunt and he's always moving forward, so I think any extra fuel that he can use or even perceive to use in his own mind to keep him training and keep him going, I think he would use that."

Kershaw allowed seven runs on 10 hits in that game and said he was haunted about it all winter.
