A lot was expected of Adam Conley right from the jump – he was ranked as high as number eight on the Marlins prospect list in 2014 according to Baseball America – and he rose quickly through the system. He made his major league debut for the Marlins in 2015.
In 15 appearances for the 2015 Marlins, including his first 11 major league starts, Conley posted a 4-1 record and a 3.76 ERA, a 1.284 WHIP, and 59 K’s in 67 innings. Out of 13 qualified pitchers on the roster, Conley was one of only five with an ERA+ over 100, just beating the mark at 101.
