The lowest round of his PGA TOUR career. @DJohnsonPGA was unstoppable on Saturday. pic.twitter.com/3AZR6wX3Hq— PGA TOUR (@PGATOUR) June 27, 2020The 2014 champion, Kevin Streelman (-15), shot a 7-under 63 to sit in outright third, with Mackenzie Hughes (-14), Bryson DeChambeau and Kevin Na (-13) all in the hunt.There was disappointment for veteran Phil Mickelson, who had led overnight. The American carded a 1-over 71 and is now six shots back.Rory McIlroy also struggled to get firing, and now the world No. 1 is eight shots adrift after a 1-under 69. Todd, who now leads at 18 under par, drained a tough 13-footer at the first and recorded four more birdies prior to the turn on Saturday.A further four gains followed on the back nine and Todd rolled a birdie putt just past the cup on the 18th that would have seen him start the final round three clear.”Whenever I get a two- or three-week stretch in a row, I tend to be playing better by the end of it,” Todd said in quotes reported by the Tour’s official website. “That’s just something I’m using to my advantage now after missing two cuts. I’m peaking in the third week and hopefully I can get it done tomorrow.”New career-low on TOUR.Third round of 62 or lower this season.Brendon Todd was in the zone today @TravelersChamp . pic.twitter.com/yW20a6QaGL— PGA TOUR (@PGATOUR) June 27, 2020Johnson, whose last win on the PGA Tour came in February 2019, was playing a couple of holes in front of Todd and also went bogey-free.After going out in 31 strokes, former world No. 1 Johnson made five birdies on the way home.The American felt he left plenty more opportunities out on the course, though, with just two of his birdies made with putts of 9 feet or more.”I really felt like I controlled the distance with my irons really well and hit tons of good shots,” he said. “I had a lot of really good looks at birdie.” Brendon Todd and Dustin Johnson carded career-low PGA Tour scores as the former moved into a two-shot lead from the latter on a moving day that lived up to its billing at the Travelers Championship.Tee times were brought forward for Round 3 due to the threat of inclement weather in Cromwell, Conn., and Todd — chasing a third PGA Tour victory of the season — signed for a stunning 9-under-par 61.
