Hamilton received two cortisone shots in his shoulder Tuesday, and is expected to miss the remainder of the series against the Rangers, Mike DiGiovanna of the Los Angeles Times reports. Hamilton hasn't been in the starting lineup since he was scratched Sunday due to neck and shoulder stiffness, and it looks like he'll miss at least another day or two. Depending on how his body responds to the treatment, he should return to the Angels' outfield at some point during the upcoming three-game series against the Astros. Colin Cowgill should continue to see additional reps in Hamilton's stead.
