When the Kansas City Royals picked up Jeremy Guthrie from the Colorado Rockies, they were getting a player that had suffered through the first half of the season at Coors Field. After coming to KC out of the Rocky Mountain air, he immediately picked up his game and ended with a 3.16 ERA by the time the season was over.
Guthrie will be available for free agency again this off season, but Royals GM Dayton Moore said in an interview with Ryan Lefebvre and Rex Hudler that he is hoping to keep Guthrie around for the long term:
"We're just pleased to be able to execute that deal. We felt that Jeremy might take a few starts, once he came here to Kansas City, but from our scouting judgments, and our statistical analysis, we felt that he was going to rebound at some point in time, and we know that he is a great competitor, we know that he is an extremely prepared pitcher, and a focused pitcher, and we felt that he would get better. Hopefully, we'll be able to sign him long-term, but he has earned the right to be a free agent, and I think he will probably go through the process."
Guthrie had a 3-9 record with the Rockies before moving to Kansas City and producing a 5-3 record with the Royals.
