Boston, MA (SportsNetwork.com) - The Boston Red Sox reported Tuesday that first baseman Mike Napoli underwent surgery to correct sleep apnea.

The procedure -- called a bimaxillary advancement -- was performed earlier in the day at Massachusetts General Hospital by Dr. Leonard Kaban.

Napoli is expected to return home by the end of the week.

The bearded 33-year-old finished the 2014 season with a .248 average, 17 home runs, 20 doubles and 55 RBI in only 119 games. It was a step back for the veteran infielder, who hit .259 with 23 homers and drove in 92 during the Boston's run to the 2013 World Series title.
