Kemp should be ready come spring training.
Spring training is a luxury.
Monitoring existing issues is imperative, and being sure that players aren't training in pain is an important precaution.
The early months of the season are a time to hone one's swing, improve hand-eye coordination, build chemistry in the middle infield and loosen the arms of pitchers and craft their control. Therefore, if an injury is lingering, there shouldn't be any need to push the player to participate until fully healed.
A prime example is Ryan Madson, the former Philadelphia Phillies closer, who missed the entire 2012 season with the Cincinnati Reds due to elbow ligament replacement surgery. The reliever signed a one-year deal with the Los Angeles Angels but will remain out until at least April as the team monitors his right arm.
The Miami Marlins are keeping an eye on outfielder Logan Morrison's knee, holding him back from running at full strength until the end of February at best.
Matt Kemp began upper body workouts with the turn of the new year but is still in the process of rehabbing his left shoulder, which underwent arthroscopic surgery after a nasty collision with the outfield wall in Colorado.
Physical trainers and medical staff will be on high alert in February and March.
