The hard luck surrounding the Royals potential starting rotation continued Sunday when lefty Mark Redman left spring training to have his left knee examined. He may have torn cartilage in the knee and if that’s the case, he could miss a minimum of four weeks to recover.

Redman came to the Royals in December in a trade with the Pirates.

Zack Greinke, who was also a projected starter, still isn’t back at camp after leaving on February 25th to deal with personal issues at home.
