Keefer has earned just under $300,000 from making the cut in three of six PGA Tour events this year

American Johnny Keefer is closing in on a Masters debut, having improved his position just inside the world's top 50 golfers with his best PGA Tour finish only last Sunday.

No, me neither.

It took an email from an intrigued listener to the Chipping Forecast golf podcast to highlight the curious case of the rise of Johnny Keefer.
