Rookie Adam Warren, the 24-year-old righthander taken in the fourth round of the 2009 draft out of North Carolina, has had an up-and-down year with Triple-A Scranton, going 5-5 with a 3.86 ERA. He pitched very well until his last couple of outings, in which he was 1-0 with a 4.80 ERA in 15 innings.

"He's progressing," one minor-league talent evaluator said of Warren late last week, speaking before the Yankees' rotation took a double hit yesterday. "Not quite ready yet, but getting there."

But Cashman said of Warren yesterday, "He's earned the right" to get the call.
