Mauricio Dubon hit a walk-off single to left field with two outs in the 10th inning, and the Houston Astros completed a three-game series sweep of the Minnesota Twins with a 2-1 win on Sunday. Dubon drove home Jake Meyers with a high fly ball off Twins reliever Cole Sands (3-3) that left fielder Willi Castro failed to catch at the wall. Meyers opened the bottom of the 10th placed at second base, but had not moved up after a ground out and a strike out.
