Miley (3-3) was locked in a scoreless battle until the Marlins scored twice in the sixth inning. The left-hander was charged with two runs on five hits and a walk, while striking out six. Miley has lost three of his last four starts.

"I felt good out there," Miley said. "I was making pitches and throwing strikes. Just a couple of bad pitches cost you late in the game, especially in a game like that where it's 0-0. You've got to do better job."

Miley will pitch Saturday against the Padres. Miley lost to San Diego on May 3, allowing four runs on nine hits and three walks in five innings.

"I was sort of messing up," Miley said. "Early in the game I was hitting spots and pitching down in the zone but then, just like that, I couldn't get it down anymore. I left pitches up and they capitalized."

Miley allowed seven runs, which were the second-most in his career. According to MLB.com, entering the game Miley had held hitters to a .178 batting average on his first 45 pitches but batters had hit .353 from his 46th pitch on.

"He didn't make the pitches he needed to make," Arizona manager Kirk Gibson said. "This team, you don't want to give them anything because you know they are going to hit a home run. That is what they do well. We put guys on and they hit home runs."

Miley will face the Braves' 12th-ranked offense Monday, and then gets a nice reprieve as he closes out the week Sunday against a Marlins squad that ranks near the bottom in every offensive category.

Miley's strikeout rate leaves a bit to be desired for a pitcher with his kind of ERA, but with two starts, that should not be a concern. There is little reason not to put Miley to use in Week 7.
