Mickleson today was quite awesome, however, why cut off the records prior to fifty years ago?
An old friend, Bobby Locke, had some astounding results in the US back in '47 and'"48.
In total he spent just over two-and-a-half years playing in the USA, competing in 59 tournaments, winning 11 of them, finishing runner-up on 10 occasions, taking third eight times and fourth five times. His 16-shot margin of victory in the Chicago Victory National Championship in 1948 remains a PGA record to this day.
