Deva has bursitis. What MOST likely happened to cause this injury?

Bursitis is inflammation of a fluid-filled sac that cushions a joint, often caused by repeated friction or overuse. Repeatedly using her shoulder during softball season could irritate the bursa, so overuse is the most likely cause. The other choices describe dehydration or injuries more associated with twisting or straining muscles and ligaments.
