SAN DIEGO -- As Patrick Reed was finishing up his practice round on Tuesday in preparation for this week's U.S. Open, he threw two balls into the rough on the ninth hole of the South Course at Torrey Pines.
One ball hopped into the rough, the other in the kikuyu, an aggressive and rapidly growing grass.
"It's nasty," Reed said. "[The ball] in the kikuyu sat up because it's so thick, actually sat high, where I felt like I could almost hit driver off of it. The other one was maybe 3 feet from it and sank to the bottom.
