Justin Morneau and Oswaldo Arcia homered as the Minnesota Twins beat the Houston Astros 3-2 Sunday for a three-game sweep.
Four Twins relievers combined for four scoreless innings, sending Houston to its fourth straight loss.
Arcia led off the seventh with a home run that broke a 2-all tie. He connected against Brad Peacock (1-4), who was promoted from Triple-A to make the start and struck out 10.
Caleb Thielbar got two outs for the win and Glen Perkins pitched a perfect ninth for his 27th save.
The Twins hadn't swept a series, or won three games in a row, since June 18-20 against the Chicago White Sox.
