Andersson has moved into the women's lead for the first time with 151 points, while Koivuniemi leads the men's rankings with 233 points. The World Bowling Tour points system is based on a continuous two-year cycle, so points earned in 2011 are added to points earned in 2012 to determine the points list.
At the 42nd Brunswick Ballmaster Open in Helsinki, Finland, the opening event of the 2012 season, Andersson picked up 40 points for a second-place finish among the women's field. USA's Carolyn Dorin-Ballard, who did not compete in Finland, is in second with 145 points.
Sweden's Nina Flack remained in the top three by earning 15 points to bring her total to 135, while Finland's Krista Pöllänen, who won the women's rankings at the Ballmaster for the second straight year, moved her up to fourth-place total to 130 points.
