Marlins manager Mike Redmond officially announced the starting rotation heading into the season following Thursday's 6-4 win over the Cardinals.

Reigning National League Rookie of the Year Jose Fernandez will pitch Opening Day followed by right-handers Nathan Eovaldi, Henderson Alvarez, Jacob Turner and Tom Koehler.

Miami's pitching staff entered Thursday with the second-lowest ERA (3.52) in the NL this spring. It posted a franchise-low 3.71 ERA in 2013.

"I'm excited," Redmond said. "Jose's obviously our main guy and our starting Opening Day pitcher. The other guys are young guys with arms. I know everyone makes a big deal where they all fall in line, but really after Opening Day it doesn't matter. It's guys' jobs to go out there and keep us in ballgames. For me it's more of a battle to get into the rotation, and that's really what we saw."

The first four starters were all but official. The fifth spot, however, was up for grabs entering spring training.

Koehler, who will start Saturday's exhibition against the Yankees, is 1-1 with a 1.50 ERA in five games (four starts) this spring. He finished last season as the fifth starter.
