The 34-year-old right-hander did his part, but "very good" wasn't enough to snap the Marlins' road slide. Marlon Byrd homered off Haren in the fourth inning, and the Reds rolled to a 5-0 victory at Great American Ball Park.
Like he's been all season, Haren was reliable, giving up two runs on four hits with six strikeouts over 6 1/3 innings. The second run he was charged with came in the seventh inning, when Steve Cishek gave up a pinch-hit single to Skip Schumaker that scored Tucker Barnhart, who had doubled off Haren.
"Dan pitched a heck of a ballgame," Miami manager Dan Jennings said. "To give up one run here in this ballpark, and it was a Great American Ball Park home run he gave up here. He really threw the ball outstanding. We couldn't supply any offense."
Jennings was referring to Byrd's homer to center, which was projected by Statcast™ of traveling 401 feet. In spacious Marlins Park, it doesn't leave the playing field.
