Tiger Woods is seven strokes back of the leader, Webb Simpson, after two rounds of the Dell Technologies Championship.
Woods shot a 5-under 66 on Saturday, a stark improvement from his 1-over 72 on Friday, but it paled in comparison with Simpson's round. The 33-year-old Simpson shot an 8-under 63 on Saturday, complete with six birdies and one eagle.
Simpson sits at 11-under through 36 holes, one stroke ahead of Tyrrell Hatton and Justin Rose. Woods is at 4-under, tied for 21st.
