Reds 6, Astros 0
Jay Bruce homered for the third straight game and drove in four runs and Johnny Cueto pitched seven shutout innings to improve to 3-0 for host Cincinnati.
Bruce's sixth homer - a two-run shot to right in the fifth inning - gave the Reds a 6-0 lead. His two-run double off the left field wall just inside the foul line made it 4-0 in the third.
Cueto scattered five hits as the Reds improved to 4-1 in his five starts and was the beneficiary of some excellent defense. The best play was provided by shortstop Zack Cozart, who dove and made a backhanded stop of J.D. Martinez's line drive into the hole and threw him out while sitting on the ground in the sixth.
Houston starter Lucas Harrell (1-2) allowed six runs - five earned - and nine hits in six innings.
The Reds took a 2-0 lead in the first. With two outs, Joey Votto doubled and scored when Astros center fielder Jordan Schafer played Brandon Phillips' line drive into a triple. Scott Rolen followed with a single to right.
Schafer singled in the fifth and has reached base safely in all 21 games, the longest streak by an Astro to start a season since Ricky Guiterrez’s 23-game run in 1998.
