Koepka takes Masters lesson into PGA Championship title defence

Brooks Koepka left last month's Masters embarrassed by his performance and hopes the "punishment workouts" imposed on him by his team as a result will lead to a successful title defence at this week's PGA Championship.

Koepka has firmly established himself as a PGA Championship specialist and his eight top-15 finishes over the last 10 editions of the major include a trio of wins.

Much of the build-up to this year's PGA Championship has centred on the
