Lee Jae-hak (Korean: 이재학; Hanja: 李在學; born October 4, 1990, in Daegu, South Korea) is a starting pitcher playing for the NC Dinos of the KBO League.
In the 2010 KBO Draft, Lee was selected by the Doosan Bears as the tenth overall pick.
Lee struggled with his command through the 2010 season, however, posting a 5.01 ERA in 23+1⁄3 innings pitched as a relief pitcher.
Lee spent the Dinos' inaugural 2013 KBO campaign as a solid part of the starting rotation, alongside former MLB pitchers Charlie Shirek, Adam Wilk and Eric Hacker.
Lee pitched his first complete game, a two-hit shutout, on July 31, 2013, against the SK Wyverns.
