APPLETON, Wis. -- CJ Filipek homered and drove in four runs Sunday to lead the Lawrence University baseball team to a 5-3 Midwest Conference win over Grinnell College at Whiting Field.

After an out, Filipek doubled to score both runners for a 2-0 lead. Shane Santaga later delivered a triple to score Filipek, and the Vikings led 3-0. 
    Grinnell (16-12, 4-5) chipped away and scored single runs in the third, fourth and fifth to tie the game. 
    Taylor Freeman then started a rally for the Vikings in the seventh with an infield single. Filipek then belted a two-run homer, and the Vikings led 5-3.
    Reliever William Polanco worked around a pair of Grinnell singles in the eighth with two big strikeouts to retain Lawrence's lead. Shane Foley came on in the ninth and worked around an infield single to record his fourth save of the season.
