On the PGA Tour, these ~~guys~~ rookies are good

Emiliano Grillo? Smylie Kaufman? If you've found yourself wondering who these players winning on the PGA Tour are the past two weeks, you're not alone. Here's what Golfweek Senior Writer Alex Miceli tweeted during Sunday's final round of the Shriners Hospitals for Children Open:

Again, that's the senior writer of a major golf publication.

Of course, we should all expect surprises in the fall portion of the PGA Tour's wrap-around season, now in its third session. From Jimmy Walker in 2013 to Robert Streb last year, this softer section of the schedule has been the springboard to some unlikely great campaigns. But so far, 2015 has been even more of an eye-opener.

Kaufman's Sunday 61 in just the second start of his rookie season was nothing short of remarkable. The 23-year-old LSU product who earned his card through the Web.com Tour was nine under over his final 11 holes, and then watched everyone from veterans Kevin Na and Jason Bohn to fellow rookies Patton Kizzire and Brett Steigmaier try (and fail) to catch him for the next two-plus hours.
