Ivan Nova is 1-4 in his last eight starts. Nova surrendered seven hits and six runs in six innings against the White Sox on Tuesday night.

"He's struggled. There's no doubt the second half, he's struggled," Joe Girardi said. "He has not located like he did the first half, and his off-speed has not been consistent. You just got to keep working. That's all you can do."

Nova, who was 16-4 with a 3.70 ERA in 2011, is 11-7 with a 4.92 ERA this year.
