Johnson in front

Golf: Now that he’s finally won again, Dustin Johnson is starting to look as dangerous as ever. One week after he ended a five-month dry spell brought on by a back injury, he easily handled the early cold and a steady win at TPC Boston for a 5-under 66 to take a oneshot lead in the opening round of the Dell Technologies Championship on the US PGA Tour. And the world’s No 1 golfer made it look easy on a tough day for scoring starting with a 35-foot birdie putt on No 10. He made the turn with a 6-iron from 220 yards into 4 feet for eagle. New Zealand golfer Danny Lee was a long way back in a tie for 75th with a four-over 75.
