Talk about a rough start to the season: First Alex Rodriguez is outed as the most famous steroid user in baseball. Then, just as he is beginning his effort at redemption, he discovers a hip injury that will keep him out for six to nine weeks. At least his arthroscopic surgery today in Colorado was a success. Dr. Marc Philippon, known as “the hip doctor to the stars,” confirmed the good news: “Alex is doing very well. There were no surprises.” If all goes well, the Daily News reports, A-Rod could be swinging a bat by the end of the week, and back on the field at the new Yankee Stadium in two months.
