One of the top prospects in the league could miss a significant amount of time after injuring his leg during a freak play on Sunday. Tatis suffered an undisclosed hamstring injury in the 10th inning of San Diego's loss to Washington after making an awkward stretch while covering second. Tatis is now slated to undergo testing to determine the severity of the strain. Tatis will likely undergo an MRI after which a classification of the strain will be assigned to the injury.
The least severe classification is a Grade 1. These injuries are considered mild and are marked by microtearing of the tissue. The injured athlete often reports pain with movement, though little to no loss of function occurs. In a more moderate Grade 2 strain, damage occurs to actual muscle fibers. As a result, Grade 2 injuries are commonly referred to as partial tears. Unlike Grade 1 injuries, Grade 2 strains usually are accompanied by a loss of function as the strength and range of motion are negatively impacted. These injuries are also particularly difficult to manage due to a complex healing process.
Anything rated as a Grade 3 or higher is considered severe and the tear is often complete. Grade 3 strains are accompanied by a loss of both stability and function and often require surgery.
The natural healing process for muscle injuries occurs in multiple stages. During the initial inflammatory phase, swelling and clotting occur at the injury site. The next step is the
