Norén went on 65 strokes, six under par, the second day when it stopped blowing at Yokohama GC.
It was a lovely day, the weather was better so it was easier to reach the greens, says Norén at the press conference.
Yesterday it was brutally difficult to try to get everything right.
Norén is a total of -8, four strokes after the leader Max Greyserman, USA. The Swede shares second place with Schauffele and Alex Smalley, USA.
A month ago, he took his second win on the European Tour, DP World Tour, in a short time when he won the British PGA Championships with a very strong starting field. He says that what he takes with him from there is that not all strokes have to be good.
One should stick to one's plan, one's routines, because then the good game comes. I'm trying now to get my game more neutral and not have any crazy routines in putting and swings.
Norén admits that he felt a little rusty after having a playing break for a few weeks to be vice-captain for Europe's Ryder Cup team.
It was nice to get a few training days last week.
