Ex-UCLA pitcher Trevor Bauer looks strong

SCOTTSDALE, Ariz. -- Trevor Bauer made it look easy.

Making his debut against big leaguers, the No. 3 pick in last June's draft retired all six batters he faced Saturday and an Arizona Diamondbacks split-squad and the Colorado Rockies tied 1-1 in 10 innings.

The 21-year-old right-hander from UCLA struck out two and induced four groundballs in his outing.

"At the core level, you throw strikes. They're hitters. They still have to hit it," Bauer said. "It was more of a competition against myself, as it always is, to try to see if I can execute pitches."

Bauer struck out Dexter Fowler and Tyler Colvin, and he got Carlos Gonzalez, Troy Tulowitzki and Michael Cuddyer to ground out. He threw seven of his 22 pitches in the first innning.

"Today was a pretty efficient outing, especially for the first one of the spring," Bauer said. "I was pleased with my control and command and pretty happy with all of it."

As part of his warmup routine Bauer played long toss in the outfield, throwing up t0 360 feet on the warning track.

In three seasons, Bauer went 34-8 with a 2.36 ERA for UCLA, winning the Golden Spikes Award for the top college player. He went on to pitch in high Class-A and Double-A for the Diamondbacks.

Bauer started Saturday in place of prospect Tyler Skaggs, who was scratched because of tenderness in his left shoulder. Arizona manager Kirk Gibson liked Bauer's debut against major leaguers.

"Some of his secondary pitches were better than I've seen any time he's thrown so far," Gibson said.
