Boston Red Sox baseball player Mike Napoli recently underwent surgery for sleep apnea and recounted the details to Comcast SportsNet.

Napoli had been diagnosed long ago with a sleep disorder, a condition he seemingly managed for a while with the help of a CPAP (Continuous Positive Airway Pressure) mask, medication and a dental mouthpiece.

But as Napoli got older, the problem worsened. He found it virtually impossible to get quality sleep and lacked energy, to the point where he would often nap before games rather than take batting practice.
