Only 58 of 119 players completed the second round before play was suspended in pouring rain. After a four-hour delay, organizers said the round would resume Saturday.
Rains at the 7,154-yard Le Meridien Moscow Golf and Country Club also forced 27 golfers to complete their first rounds on Friday.
Johansson, tied for seventh at 3 under after the first round, made 10 birdies, including five in a row starting from his 13th hole. He finished 13 under at 131.
'It was certainly the best putting I have done in a long, long time,' Johansson said. 'I have been putting well enough and I actually missed a couple from short range in the early part of my round but I did make a lot of long ones.'
