1. Bryce Harper, C/OF - Despite a rough professional debut in which he struck out in his only two at bats, Harper remains at the top of the list. Like any player who spent two months or so away from organized baseball, significant rust was to be expected (particularly for one with such high expectations at just 17 years old). The fact is that Harper remains preternaturally gifted with prodigious power and, quite honestly, his ceiling is far greater than that of any prospect in the organization. There is a considerable learning curve associated with the transition from junior college baseball to the professional ranks and, let's remember, he was the number one overall pick for good reason. It will be a treat to watch Harper ply his trade in what will be his first full season of professional ball next year, regardless of the position he ultimately plays.
2. Danny Espinosa, SS - From two-time MLB Future's Game alumnus to major league regular, it appears that Espinosa has completed his journey to the big league and is there to stay. After hitting .295/.349/.463 in 24 games at AAA Syracuse, the Nationals rewarded him with a call-up to the major league club. Espinosa burst onto the scene with nine hits in his first 18 at bats, including three doubles and three home runs. Moved to second base to accommodate Ian Desmond, Espinosa came down to Earth by the end of the year, finishing with six homers and a .214/.277/.447 line. However, as his offense declined, his renowned defense remained solid. Espinosa committed just one error during his Nationals' tenure and his performance should give both the front office and managerial staffs pause as to whether or not he belongs as second or shortstop full-time.
3. Derek Norris, C - This has undoubtedly been a rough year for Norris. After his extensive successes in 2009, myriad injuries impeded his adjusted to High-A Potomac. Though his batting average and slugging percentage dropped 51 and 94 points from last year's totals, Norris still managed to get on base at an impressive .419 clip. He remains a work in progress behind the plate (though he did throw out 51% of attempted base stealers); however, his calling card is and will continue to be his bat. It's only fair to withhold judgment on Norris until he is healthy for another full year and has a chance to redeem himself in 2011.
