The Kevin Na Playing Partner Penalty: .4 Strokes Per Round

On Morning Drive this Sunday Charlie Rymer talked at length about the cruelty of a Kevin Na pairing because of the added burden it places on his playing partners. Robert Garrigus was too kind to go there, but his caddy Brent Henley concurred.

Well now Luke Kerr-Dineen and the GolfDigest.com team have crunched the numbers and determined that players average nearly a half-shot higher than their normal round scoring average when getting paired with one of the world's slowest golfers.

How'd it turn out? From the start of 2012 through the 2014 Valspar Championship, Kevin Na has played with 220 PGA Tour golfers. On average, those 220 golfers shoot about 0.4 strokes higher when playing with Na. That's almost half a stroke, meaning that if someone plays with Na in all four rounds of a tournament, he'll be expected to shoot 1.6 strokes higher than if he played with someone else.
