Matt Wieters’ first grand slam since 2013, and the third grand slam of his career, put the Washington Nationals up 8-4 in the eighth inning this afternoon in Wrigley Field, and the Nats took the series finale and season series from the Chicago Cubs with a 9-4 win.
Nationals’ rookie Erick Fedde held Chicago to two runs through five innings, but Cubs’ catcher Willson Contreras, who’d already homered in the fourth, got to Washington’s 24-year-old right-hander again in the sixth, sending his 21st HR of 2017 out to left in front of Kyle Schwarber, who followed with the second of back-to-back HRs that put the home team up 4-1 after six.
