Jeremy Guthrie and the Baltimore Orioles are doing just fine without each other.

Guthrie lost 60 games over a four-year stretch with the Orioles before being traded to Colorado in February 2012 for pitchers Jason Hammel and Matt Lindstrom. Now he's back in Baltimore for the first time, poised to face his former team Thursday night as a member of the Kansas City Royals.

Revenge will not factor for Guthrie, who says, "That's a trade I would have made in a heartbeat."

Hammel and Lindstrom played huge roles in the Orioles' playoff push last year. Guthrie struggled with the Rockies, but this season the 34-year-old right-hander is off to a 4-0 start with the surprisingly successful Royals.

Guthrie says his time in Baltimore was, "a huge plus, just wonderful."
