Leave it to Texan Jimmy Walker to clean up around the Redstone Course. The 32-year-old -- winless in 119 starts -- just birdied the par-4 sixth -- his 15th hole of the day -- to get to 8 under.

Walker has already had a big year. He was fourth in both the Northern Trust Open and the Sony Open, and he tied for ninth in the T&T Pebble Beach National Pro-Am after shooting 63 in the third round.
