While Joe Girardi hinted he was considering a six-man rotation earlier in the week, that was likely just to give Nova some peace of mind in preparation for his start on Friday.
The team called up right-hander Lance Pendleton to take Nova's spot on the roster, but he'll likely be replaced by Hughes for Wednesday's game in Cleveland.
Hughes has spent the last three months on the disabled list with what was officially called right arm inflammation but was more because of the mystery of his missing velocity. During his first three starts of the season, he was averaging 89.3 mph on his fastball and was consistently in the low 90s in his last start in the minors, Wednesday at Double-A Trenton.
Nova is 8-4 with a 4.12 ERA and is 4-1 with a 3.35 ERA in his last six starts. The Yankees, who started the season with several questions in their rotation, will start the second half of the season not only with a full rotation, but also Nova in reserve if one of their other starters is hurt or ineffective.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
