Editor's note: Over the next two weeks, we will examine the top 10 prospects in the A's organization. For each player, we will provide a scouting report and a realistic timetable for reaching the major leagues, as well as what he needs to do to stay there.
No. 10 - Nick Allen, SS/2B
The A's selected Allen out of high school in the third round of the 2017 MLB Draft and he is beginning to develop into the shortstop they hoped he would be. At just 5-foot-9, the 21-year-old is far from imposing physically, but he is a defensive wizard.

Allen has tremendous range and a cannon for an arm, with MLB Pipeline assigning him a 65 fielding rating on the 20-80 scale and an arm grade of 60. There has never been any question about his defensive ability, which is already MLB quality. Now he's beginning to show improvement at the plate as well.
Allen struggled in 2018 at Class-A Beloit, slashing just .239/.301/.302 in 121 games. But this past season at High-A Stockton, that slash line shot up to .292/.363/.434, with improved power numbers across the board.
Allen also has above-average speed, with a 60 rating from MLB Pipeline. He stole 37 bases in 193 games over the past two seasons.
Allen can play shortstop and second base, both potential positions of need for the A's in the near future. Marcus Semien is set to become a free agent after the 2020 season and Jurickson Profar is far from a sure thing to return. Youngsters Jorge Mateo, Franklin Barreto, and Sheldon Neuse could also be options at the middle infield positions, but Allen has a great chance to earn a spot down the road.

Realistically, Allen doesn't figure to join the A's until at least 2021, with 2022 seeming more realistic. He just turned 21 earlier this month and has yet to play a single game above High-A.
Allen will likely start the 2020 season at Double-A Midland, with an opportunity to move up to Triple-A Las Vegas, based on his performance. If he continues to progress offensively, he could certainly earn a major league call-up at some point in 2021.

Allen has already added some strength, which has been reflected in his increased productivity at the plate. He will need to continue his work in the weight room, without losing his speed, which should be his biggest weapon offensively.
While Allen will never be a power-hitter, he can use his speed to wreak havoc on the basepaths. If he maintains his magical defensive prowess, he has an opportunity to develop into a solid major leaguer for Oakland.
