Marlins tab prospect Heaney for start vs. Nats

MIAMI -- Before calling it a season, the Marlins are giving their top prospect, Andrew Heaney, one final start. The team announced Wednesday that they are pitching the left-hander on Friday in the second game of a doubleheader at Washington.

Jarred Cosart will get the nod in the first of the day-night twin bill at Nationals Park. Heaney will be making his first big league start since July 5, but the 23-year-old will have some familiarity with Washington, having pitched three innings of scoreless relief against them on Sunday at Marlins Park.

When the season started, Heaney was ranked by as the top lefty prospect in the game. The ninth overall pick in the 2012 First-Year Player Draft, Heaney opened the season at Double-A Jacksonville. He moved up to Triple-A New Orleans, and he made his MLB debut on June 19 against the Mets.

Heaney has made four big league starts, and took the loss in three of them. He seeks his first big league win.

After being called up in September, Heaney has made two relief appearances, allowing two hits while striking out four in 4 2/3 innings.

"He's done a good job," Miami manager Mike Redmond said. "I think it's the right time in the last couple games of the season to get him in there, especially having a doubleheader. It worked that the last time that he pitched was the three innings. He's available for that day. We'll let him go out there and let him pitch and get a start."

Heaney combined for a 9-6 record with a 3.28 ERA in 24 Minor League games, with 23 starts this season. The lefty has thrown 163 2/3 total innings, with 25 1/3 with Miami.

The rotation for the Nationals series will also feature Nathan Eovaldi starting on Saturday and Henderson Alvarez on Sunday in the season finale.
