Rooker went 0-for-4 with four strikeouts Monday in the Twins' 11-1 loss to the White Sox.
The Twins continue to deploy Rooker as their No. 2 hitter, but his poor results of late could prompt manager Rocco Baldelli to push the rookie down in the batting order. Through eight games in August, Rooker has gone 4-for-34 while drawing only two walks against 11 strikeouts. His batting average now sits at .168 for the season.
