The Orioles have called up 2B /SS Jackson Holliday (son of Matt Holliday)
He's 20 years old, and looks about 16.
He is MLB's #1 ranked pre-season prospect.
In year's past, you NEVER would have seen a prospect like this brought up so early. Not that his stats didn't warrant it - he's been absolutely destroying minor league pitching - but teams would always wait until later in the season to protect an extra year of team control over the player. A new MLB rule doesn't really change team control stipulations, but if a player is ranked in the Top 100 Prospects and secures a full year of service (basically brought up in the first 2 weeks of the season...172 days on the roster) AND that player factors into a postseason award (ROY, top 3 in either MVP or CY) - the team is awarded a 1st Round Draft Pick for the following season. It's knows as the PPI (Prospect Promotion Incentive). MVP and CY awards are 3-year windows where the team can get the extra 1st rounder - it doesn't have to happen in year one.
He's had a rough go so far.
0-11 in his first 3 games
