A similar shift was made the previous year, as the date was moved from Aug. 15 to Aug. 17 so it could land on a Monday. The deadline only applies to players with remaining college eligibility.
Last year, two first-rounders with remaining college eligibility went unsigned past the midnight ET deadline: left-hander Matt Purke (drafted by the Rangers) and second baseman LeVon Washington (Rays).
A high-school player who doesn't sign by the deadline and enrolls in a four-year college isn't eligible for the First-Year Player Draft again until after his junior year of college or his 21st birthday. Those who go on to attend junior college are eligible after their freshman and sophomore years. And college juniors who don't sign are available in the following year's Draft.
