Here are the positive WAR contributions at the MLB level for all players drafted by the Royals since 2010 (when AA took over in Toronto):
2010: Christian Colon (1.3), Kevin Chapman (0.8), Jon Gray (0.2)
2011:
2012:
2013:
2014: Brandon Finnegan (0.8)
And the Jays:
2010: Aaron Sanchez (3.2), Noah Syndergaard (2.5), Justin Nicolino (0.3), Sam Dyson (1.6), Dalton Pompey (0.7), Kris Bryant (6.0)
2011: Daniel Norris (0.5), Anthony DeSclafani (1.0), Aaron Nola (1.8), Kevin Pillar (5.9)
2012: Marcus Stroman (3.2)
2013: Kendall Graveman (1.3)
