The Los Angeles Dodgers have announced that Julio Urias will start Wednesday's Game 4 of the NLCS against the Chicago Cubs.

Urias will become the youngest postseason starting pitcher in Major League history, surpassing a mark previously held by Bret Saberhagen, who took the mound at 20 years, 175 days old in 1984. Urias will be 20 years, 68 days old when he pitches in Game 4.

"Julio, I think that we expect him to just go out there and compete, use his pitch mix and go after these guys," Dave Roberts said. "Give us a chance to win a baseball game. It's what Julio's done all year long."

Urias pitched just 14 innings in September as the Dodgers curtailed his innings. He didn't make a start in the NLDS, but pitched two scoreless innings in Game 5.
