How many pitchers drafted in the supplemental and later rounds of the draft since 2012 should realistically be contributing to a playoff caliber team? I counted. The number of players drafted with the 31st and later pick of the draft since 2012 who have contributed at least 1 bWAR to one of the 13 teams (5 in the AL and 8 in the NL) competing for the playoffs is 14. Brian Johnson, Chad Green, Lance McCullers, Lou Trivino, Sean Manaea, Nick Pavetta, Zach Eflin, Josh Hader, Austin Gomber, Jack Flaherty, Scott Oberg, Dylan Floro, Alex Wood, and Ross Stripling. 8 of the 14 were drafted in 2012, 4 were drafted in 2013, and the two Cardinals were drafted in 2014. If you want, you can add Victor Arano, a 2013 amateur free agent signing to make it 15. 8 of these 15 weren't originally drafted/signed by the team they currently play on, but were acquired by trade.
