The following article details the 2012-13 Toronto Maple Leafs Prospect Award winners. Morgan Rielly was the big winner with three awards, while Tony Cameranesi also took home multiple awards. The annual award winners were selected by the author with input from Hockey's Future staff members.

Most Improved: Garret Sparks, G, Guelph Storm (OHL)

A seventh-round pick from the 2011 NHL Entry Draft, Garret Sparks has developed much more consistency in his game this past season. After a slow start where he posted a 3.74 goals against average and .895 save percentage in September, then a 3.78 goals against average and .898 save percentage in October, Sparks was very consistent the remaining five months of the season. His best month came in January where Sparks had boasted an impressive 7-1 record. He had two shutouts during that month and posted a 1.62 goal against average and .940 percentage. He has improved his numbers across the board with a career high 60 games played this season. Among his peers, Sparks was ranked seventh in goals against (2.65), fifth in save percentage (.917), first in minutes played (3440), and he was also tied for first with 36 wins.

Best Defensive Prospect: Morgan Rielly, D, Moosejaw Warriors (WHL)

At this point, it is fairly easily to say that Morgan Rielly is a prospect that stands alone in the Maple Leafs system. Not only is he the team's best defensive prospect, he is their best prospect overall. Rielly has an elite offensive game with high end hockey-IQ that should aid in his transition next season as he pushes for a roster spot. His skills have been on display at times with the Marlies, who he joined at the end of his WHL season. While he has not put up jaw dropping numbers, he earned himself a spot on the team's playoff roster. With the Maple Leafs push for patience over the years, there's a strong possibility Rielly finds himself back with Moosejaw in 2013-14. Should he return to major junior hockey next season, he will be one of the top players in his position at the CHL level.
