Texas Rangers outfielder Shin-Soo Choo has a bad shoulder, having left camp earlier this week to get a cortisone shot in his left shoulder.
The official line from the Rangers is that this is no big deal, and Choo may be back in the lineup as the DH this weekend, but this is something worth keeping an eye on. Choo turns 37 in July, and has dealt with physical issues throughout his time with the Rangers, particularly in 2014 (when he was slowed by back issues) and in 2016 (when he appeared in just 48 games).
