SECAUCUS, N.J. — The Phillies selected California high school outfielder Mickey Moniak with the top pick in the Major League Baseball draft Thursday night.

Moniak, from La Costa Canyon High School in south Carlsbad, became the first prep outfielder chosen No. 1 overall since Tampa Bay drafted Delmon Young in 2003.

The selection, announced by commissioner Rob Manfred at MLB Network studios, marked the first time the Phillies led off the draft since they took Miami slugger Pat Burrell in 1998.

With no consensus No. 1 talent this year, there was plenty of uncertainty about whom the Phillies would grab as they went on the clock.

“I definitely wouldn't say there's pressure,” Moniak said in an interview on MLB Network. “I'm excited to hopefully prove the Phillies right.”

The left-handed-hitting Moniak is 6 feet 2 and 190 pounds and is considered a five-tool talent whose stock rose throughout his senior season. He consistently hits to all fields with solid power to the gaps. Moniak is also an outstanding defensive player who has good speed and is expected to remain in center field.

Tennessee third baseman Nick Senzel went second to Cincinnati, giving the Reds a slugger who might someday provide some pop in the middle of their lineup.

The Braves took high school right-hander Ian Anderson with the third pick. The 6-foot-3, 170-pound pitcher from Shenendehowa (N.Y.) has a fastball that sits in the 91- to 94-mph range, and he mixes in a solid breaking pitch with terrific control.
