New York ? Justin Upton was simply too good for the Arizona Diamondbacks to pass up.

Despite having a few talented shortstops already in their minor-league system, the Diamondbacks added another when they made the Virginia high schooler the top pick in the baseball draft Tuesday.

“I think everybody saw the same thing,” general manager Joe Garagiola Jr. said. “They saw an extremely gifted athlete. That understandably catches your eye. And when you’re around him, and around his family, you get the feeling that these people have their values together.”

Upton and his brother B.J., the second pick in 2002 by Tampa Bay, are the highest-drafted siblings. They weren’t the only family with big news on draft day.

Roger Clemens’ son, Koby, a third baseman from Memorial High in Houston, was taken by his father’s Astros in the eighth round. The sons of former major leaguers John Mayberry, Carney Lansford, Garth Iorg, Ivan DeJesus and Bryan Harvey were among those selected on the draft’s first day.

Upton, the Virginia player of the year who batted .519 with 11 home runs and 32 RBIs in just 54 plate appearances, joins the recently signed Stephen Drew, Arizona’s top pick last year, and Sergio Santos as top Diamondbacks prospects at shortstop. Upton, 17, was mainly a shortstop at Great Bridge High School in Chesapeake, Va., but also played third base and the outfield.

“We drafted him as a shortstop,” Garagiola said. “Those kinds of things tend to sort themselves out later on.”

Upton got the news at his high school, surrounded by about 100 family members, friends and teammates.

“It was crazy when they picked me,” Upton said. “Everybody had their reaction, and it was just a good time.”

It was Arizona’s first No. 1 overall draft selection. The Diamondbacks’ previous highest pick was No. 4 in 1999, when they took another high school shortstop, Corey Myers.

Arizona had also considered a trio of college right-handers: Wichita State’s Mike Pelfrey, Craig Hansen of St. John’s and Tennessee’s Luke Hochevar – all represented by Scott Boras. All three slid to lower slots than originally expected.
