Check Jamie Lovemark's Wedge Grooves!

It's about 1:20 into this PGATour.com recap of the Frys.com Open: I just want to know what grooves were in the wedge that refused to let Jamie Lovemark's Nike sink into the water during a sudden death playoff. New grooves? Old soon-to-be-non-conforming?

Wait, sorry, you said what?

It was probably the concrete lining? Really? But it's such a natural looking hazard. Anyway...

By the way, Lovemark may have finished tied for second, but as he explains during his post round chat, he starts the first stage of Q-school Tuesday. He also talks about the shot into 18.
