The 2018 KitchenAid Senior PGA Championship is underway at Harbor Shores Golf Club in Benton Harbor, Michigan. 

Bernhard Langer is the defending champion, but unable to play this year as he attends his son's high school graduation.

Rocco Mediate won the tournament when it was played at Harbor Shores in 2016. 

Here's a look at the TV schedule and tee times for the most historic major in senior golf.
