Eugenio Suarez hit a tiebreaking homer in the eighth inning, and the Cincinnati Reds ended the Washington Nationals’ nine-game home winning streak with a 3-2 victory.
Suarez went 3 for 4 with two R.B.I. to help the Reds stop a three-game skid. Aroldis Chapman got three outs — reaching 103 miles per hour on one fastball — for his 17th save.
Earlier in the day, the Nationals star Bryce Harper said that he would not participate in next week’s Home Run Derby in Cincinnati because his father was not available to pitch to him.
