Dave Roberts is "very hopeful" that Clayton Kershaw will regain some of his velocity next season.

The left-hander is heading into his age-31 season.

Kershaw signed a three-year, $93 million extension with the Dodgers shortly after the World Series.

His fastball hovered in the low 90s last season.

"If anyone sets their mind to something that they want to sort of tap back into, it's Clayton," Roberts said. "If you look back at what Clayton did this year, still pretty good. There were a couple of mistakes with the slider, the fastball, but he can still pitch when he needs to pitch. But I do expect an uptick in velocity next year."
