As part of a series of corresponding roster moves today the Marlins have called up stud pitching prospect Andrew Heaney from Triple-A for what will be his big-league debut at age 23.
Heaney was the ninth overall pick in the 2012 draft and ranked 30th on Baseball America’s prospect list coming into this season, improving his stock even further by posting a 2.47 ERA and 79/15 K/BB ratio in 77 innings between Double-A and Triple-A.
He projects as a potential No. 1 or No. 2 starter with a low-90s fastball and good off-speed pitches, and Heaney will step into the rotation spot created by designating veteran left-hander Randy Wolf for assignment. His debut will be Thursday against the Mets.
In other moves, the Marlins also placed outfielder Christian Yelich on the disabled list with a back injury, recalled 22-year-old outfield prospect Jake Marisnick from Triple-A, and designated for assignment veteran right-hander Kevin Slowey. It’s a busy afternoon in Miami.
