After dominating the field in the first two rounds of the U.S. Open, Dustin Johnson shot a disastrous 77 on moving day as his four-shot lead disappeared.
Johnson is in a four-way tie for the lead with defending champion Brooks Koepka, Daniel Berger and Tony Finau.
Berger and Finau, who teed off in the morning session, both shot rounds of four-under 66 and moved from seven-over and tied for 45th to three-over and a tie for the top spot.
Since Berger and Finau finished their round earlier than Koepka and Johnson, they will be in the final pairing of Sunday's championship round.
