Mike Trout of the Los Angeles Angels was placed on the 10-day IL this past Friday with a left knee contusion. The term 'contusion' shouldn't be taken lightly as bone bruising can be painful and lead to further issues. Trout suffered two separate meniscus injuries in the same knee last year, raising suspicion of early degenerative changes. The Angels' efforts to preserve his health by moving him to right field haven't prevented this injury. Despite his optimism, a full recovery may take longer than 10 days. His early power display this season shows potential, but his body's cooperation is crucial.
