CHASKA, Minn. -- Last week I told you that Sergio Garcia and Retief Goosen will be using TaylorMade's yet-to-be-released Penta golf ball here at Hazeltine. From the outside, a five-piece ball looks identical to a two-, three- or four-piece ball. They're all round, white and covered with dimples.Don't try this at home, but if you cut a few Pentas in half, this is what you'll see.
Starting at the far right, the four interior pieces are: the black core, which is solid; the gray inner mantle layer; the red middle mantle layer; and the thin, light-red outer mantle. The sliver-thin, white urethane cover is the fifth layer.Follow David Dusek on TwitterAlso See:- 2009 GOLF.com Ball Guide- See and Buy TaylorMade Balls- PGA Tour Winning Bags
