GLENDALE, Ariz. — Julio Urias‘ first appearance in a major-league game Saturday was practically over before it started.

The 17-year-old lefty threw 14 pitches in a 1-2-3 first inning against the San Diego Padres at Camelback Ranch. He struck out Will Venable swinging after falling behind 3-0 — all on fastballs — then got Chris Denorfia to ground out and struck out Yonder Alonso swinging on a slider. Three up, three down, 14 pitches, nine strikes.

Urias threw all three of his pitches for strikes. His fastball was clocked in the 93-96 mph range; his curveball in the 75-80 range and his changeup in the 75-79 range.

“I felt really happy. I was under control and not nervous at all,” Urias said through an interpreter.

With his father, Carlos, and an uncle in attendance, Urias garnered as much attention as anyone from the announced crowd of 13,232.

“It’s always been a dream of mine,” Urias said. “I’m happy to be with the Dodgers.”

Sam Demel was originally listed as the starting pitcher for the game. Urias was informed Saturday morning that the plans had changed. That only made him more comfortable; Urias started each of the 18 games he pitched last season for Low-A Great Lakes. By starting instead of reliving he had a full bullpen session before the game to get loose.

Dodgers scout Mike Brito, who signed Urias as a 16-year-old in August 2012, said the plan calls for Urias to begin the regular season at High-A Rancho Cucamonga. Based on the early returns, Urias might not need to be in the California League for long.

“I was not surprised,” Brito said. “He was very impressive.”

Brito, who also signed Fernando Valenzuela as a teenager, doesn’t think it will take long for Urias to be ready for the major leagues. Valenzuela debuted at 19 years old.

Urias said he’d like to be in the majors by the end of the season. The Dodgers have only suited up six 18-year-olds in their history and two 17-year-olds, none since Charlie Osgood in 1944. Urias turns 18 on August 12.
