Los Angeles Dodgers starting pitcher Clayton Kershaw, center, celebrates after their win against the Tampa Bay Rays in Game 5 of the baseball World Series Sunday, Oct. 25, 2020, in Arlington, Texas.
Dodgers beat the Rays 4-2 to lead the series 3-2 games.
The rookie right-hander hopes to keep the World Series from reaching a Game 7 for the fourth time in five years.
The Rays and Cash have impressed Roberts with their relentlessness, evidenced by their ninth-inning rally to win Game 4.
Hershiser, the 1988 World Series MVP, says each time the postseason is lengthened it adds another level of uncertainty to the competition.
