The Angels didn’t need an hour-long inning. They didn’t need any ninth-inning heroics. No dumping of Gatorade coolers. The Rally Monkey could’ve taken the day off. All they needed Sunday was Garrett Richards. After three straight comeback wins against the Astros, the Angels sealed a four-game series sweep with a breezy 6-1 victory, winning their 10th straight game at Angel Stadium — their longest home winning streak since 1996.
