The Royals are interested in Kevin Millwood, according to Dan Connolly of the Baltimore Sun (on Twitter). The right-hander has averaged 31 starts since his first full season in 1998, so GM Dayton Moore likely sees him as a back-of-the-rotation innings eater.
Millwood has an All-Star appearance and an ERA title to his name, but at this point he's likely to post an ERA near 5.00 with about 6.0 K/9 and 3.0 BB/9. In 190 2/3 innings as an Oriole, he posted a 5.10 ERA with 6.2 K/9 and 3.1 BB/9.
The Rockies have also expressed interest in Millwood, who could potentially benefit from a move to the NL. Since the Orioles didn't offer the 35-year-old arbitration, they won't obtain a compensatory draft pick if he signs elsewhere.
