LOS ANGELES -- Jackson Holliday, the son of seven-time All-Star Matt Holliday, was selected by the Baltimore Orioles as the No. 1 overall pick in baseball's draft on Sunday. Holliday, a high-school shortstop out of Stillwater High School in Oklahoma, is an elite hitter who made significant strides in several aspects of his game over the last year. The 6-foot-1, 175-pound left-hander hitter finished his senior season with a .685 batting average and was named Baseball America's High School Player of the Year. Editor's Picks 2 Related Holliday previously committed to Oklahoma State, where his uncle, Josh, is the head coach, but will now likely venture directly into professional baseball, where his improving quickness and arm strength is expected to keep him at shortstop. Holliday's calling card, however, is his hitting. The 18-year-old already has an advanced approach in the batter's box and accumulated 89 hits in 41 games last season, breaking the high-school record that was previously held by Philadelphia Phillies catcher J.T. Realmuto .
