11:04pm: Renck confirmed that the Rockies are out on Miles after signing Amezaga (Twitter link). Yesterday's workout sold them on his ability to help the club.
8:16pm: Utility infielder Aaron Miles is drawing interest from multiple AL and NL teams according to Troy Renck of The Denver Post (on Twitter). The Rockies were rumored to be one such team, but they signed Alfredo Amezaga to a minor-league contract earlier today. The Nationals had interest in Miles earlier this offseason as well.
The 34-year-old hit .281/.311/.317 in 151 plate appearances for the Cardinals last season, not all that far off from his .282/.321/.354 career batting line. He has plenty of experience at both middle infield spots and has dabbled at third base and in left field in his career. Miles also has five career pitching appearances (3.60 ERA) to his credit, so he can always do that in an emergency as well.
