Kevin Pietersen shows Kevin Na how to go about a tap-in!

In case you were unaware, Kevin Pietersen has got a bee in his bonnet when it comes to slow play, especially where Kevin Na is involved. And rightly so, in our view! 

Pietersen tweeted a post of him sitting in his lounge watching Na taking 1 minute 20 seconds to roll his ball home from within a foot during the final round of the Genesis Open on Sunday.

And the England cricket legend has since called Na out by showing him exactly how long it should take for a tap-in putt... seven seconds to be precise!
